Title: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: tvg on July 27, 2007, 11:29:18 PM
The latest working build:
13990, for IPod Nano 1st gen: http://tinyurl.com/2btboy


Update:
The problem starts from r14004
"Clean up PP502x CPU clock setup code and use the full 80MHz when boosted"


Hi. I'm expierenced RockBox user (Cowon IAudio X5L).
I bought used IPOD Nano 4g and installed Rockbox onto it. I'm almost satisfied, all seemed to work.
But...

MP3 can be played well. FLACs (5th level) play badly or even not play at all. I start to play FLAC and: it plays 5-10 seconds, then skips to next file. Sometimes FLAC plays straight ahead with terrible glitches in headphones. One time I even encountered a message: "bad data at address 000000..." on white screen.

But! Sometimes (i woke up in the morning, the IPOD laid on a desk overnight, untoched, calm) it playd FLAC well! I started FLAC (50 minutes), it played and played well... Then I scrolled and it still played well! The I turned ON CUE support and a bunch of other options and rebooted the RockBox.

Then the playback was broken again.

It seems that with original firmware the playback is OK. Please tell me about more steps I need to investigate the probleb. I think, the Ipod itself is not broken. Thanks.

P. S. It would be great, if it played all the files well. Very good firmware.

It helps if you give the exact text of the error message, rather than generalizing as it's very important.

Also, it helps if you tell exactly which SVN revision you're using.

Post by: tvg on July 27, 2007, 11:42:04 PM
I encountered text message only 1 time.
Usually no any messages, just terrible clicks, or usually just skipping to the next tracks.

Often the track is not played at all: it displays sign "Play" (">"), but the time is not counting and no sound.

AND: this was 27.7.2007.
Now I just installed 27.6.2007 - and it's great!

If you, developers, need, I cound use a frame and find, from what date the RockBox on Ipod Nano plays faulty.

Post by: Llorean on July 27, 2007, 11:43:04 PM
I asked for a specific SVN revision, not a date. There are many builds made each day. Are you saying you used the daily build (which we specifically do not recommend)? We even clearly state in the guidelines that you should be using a CURRENT build before reporting anything. The Daily is *not* current.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: tvg on July 28, 2007, 12:03:46 AM
SORRY, really I used current build instead of 27.7.2007.

r13860-070712 - no problem.
r14031-070727 - there IS a problem. And it hanged during playback just after I catched SVN number from About menu.

I think the problem is not in FLAC decoder, but in 'disk driver' or with memory management, because after faulty FLAC playback mp3s are also cannot be normally played.

Now I'm trying to find the daily build, which had introduced this bug.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: Llorean on July 28, 2007, 12:11:56 AM
I have no problems playing FLAC with 14031. Could you tell me a few things:
1) Have you ever in the history of owning this iPod installed iPL?
2) What firmware version is the Apple OS?
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: tvg on July 28, 2007, 12:17:02 AM
r13961-070723 - NO problems.

In next 15 minutes I will find a daily build which introduced the problem.

1) I just bought a used Ipod, in very good condition. No any history. And I'm also new to IPODs.
2) IPOD OS is 1.3.1.

P. S.: r14019-070727 is already faulty.

Post by: Llorean on July 28, 2007, 12:20:36 AM
Isolating a specific build is unlikely to help much, as I said, my iPod doesn't have the problems at all. It has something to do with the iPods themselves. There is some difference in the iPods that may be experiencing these problems. My personal current theory is that the newer retail firmware flash bootloader is the cause, but I need more people to answer my questions first.

I suspect you'll find that the problems begin where we start properly handling CPU frequency.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: tvg on July 28, 2007, 12:29:22 AM
r13990-070726 - no problems.

So the problem starts from r14019-070727.

r13->r14 => problems...
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: Llorean on July 28, 2007, 12:32:34 AM
There are 29 revisions between 13990 and 14019. I don't know what you mean by "r13->r14 => problems...", revisions 13 and 14 are years ago, and if you mean the first two digits, those really are thirteen *thousand*, nine hundred and ninety.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: tvg on July 28, 2007, 12:35:24 AM
How do I have an access to these 29 revisions?
I used this page: http://www.rockbox.org/dl.cgi?bin=ipodnano

And, of course, I meant thousands digits.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: Llorean on July 28, 2007, 12:36:52 AM
Every number, 13990, 13991, 13992, 13993, etc, is a different revision, with changes. They're accessible if you check out the source through SVN and compile. Since I'm not having the problem, you're the only person who can isolate this.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: tvg on July 28, 2007, 12:40:58 AM
I think right now I cannot compile without investigation on how to compile etc...

May be somebody will help me compiling and providing builds?
Oh I know, you all are so busy... If not, I will investigate by myself.

Post by: Chronon on July 30, 2007, 01:54:50 PM
There are quite good instructions in the wiki on setting up a development environment.  I would recommend the VMWare option as it comes pre-configured.  Search the wiki for VMWare.  There are also wiki pages (UsingSVN, SimpleGuideToCompiling) that should provide the necessary information.  There's also a dedicated forum if you need further help on that.

What versions are needed for testing?
I'm stuck in a hotel, might as well build some.

EDIT:  Building
http://rockbox.cleansoap.org/nano
Browse there for all (I believe) relevant builds.
Building still as we speak.  PM me if you want a build I haven't done yet.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: tvg on July 31, 2007, 01:39:27 PM
I already compiled and found the build that introduces the bug: it's 14004.


Please vote for the bug: http://www.rockbox.org/tracker/task/7510
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: Llorean on July 31, 2007, 02:17:15 PM
Why should people "vote for the bug"?

It's not going to magically make it more likely to get fixed.

It's not even strictly speaking a bug in Rockbox. The most likely cause is that Apple changed the way their hardware is initialized, and it's simply no longer compatible with the way we were used to using it. It's something to be fixed, but it's NOT a bug that Amiconn introduced. His changes just brought a long existing problem (that we trusted the Apple loader) to light.

It's very, very unkind to blame someone for a problem when you don't even understand what the problem is.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: tvg on July 31, 2007, 02:30:34 PM
I don't know what to do, sorry.
I can change anything you like and I'll go. Yes, it's no longer compatible.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: bluebrother on July 31, 2007, 04:26:34 PM
well, the key for fixing a bug is *reproducing* it. Apparently you're the only person experiencing this problem, at least in this thread. So instead of asking about votes (which are ignored anyway, and even if not, unless someone can reproduce the problem votes won't change anything) you should try to (1) narrow down the bug and (2) try to figure out how others can reproduce the issue.

I narrowed the bug to one build it appears.
And no, I'm not the only person apparently.
May be this topic can be deleted though, because here in this part of forum it's of no use.

Hey guys, first post, I'll see if i can add anything to this discussion. I am experiencing similar  symptoms with a 2Gb 1st gen nano after updating to one of todays builds. The difference being that it is doing it with all of the songs i have and erroring out during forward skips. i experienced a couple of error codes but it was while driving, i will see if i can reprodue them and post
I'm still wrapping my brain around the builds (friquency of, and tracking the version number) and will post when i track down the information if it might prove helpful.
let me know if it will or not or if we need to move the thread so i can keep up.
thanks....rockbox rocks :)

fritzgutten, try build 14003 or archived daily build of 26.07.2007. Should work.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: fritzgutten on August 02, 2007, 02:32:26 PM
Ok, I tried the build from 26.07.2007 and now it errors out during playback.

the real question I have at the moment, is ...have i loaded it properly? am I doing something incorrectly?
the apple firmware/bootloader has not (to my knowledge) been updated for over a year.
the rockbox bootloader also has not been updated for about the same amount of time. Do i need a newer bootloader, how do I check the version of the bootloader?

otherwise I think I'll work my way back through the various builds and see if I can get something better going on.

thanks, Fred

Hold the >>| button as the iPod boots.  What bootloader version is displayed?

Post by: fritzgutten on August 02, 2007, 04:04:07 PM
ok, the forward button doesnt seem to effect the booting process at all, so i just booted it 4 times getting a little bit more of the bootloader version number each time.
it appears to be : 20060126-1829 which would be from january 26 2006?

 ;D ok taken care of things are looking great so far....2-3 mins :) I will post an update after some time of playing with it.
thanks guys.

there isnt any recommendation in the instructions for bootloader update... except to say that the bootloader is rarely updated.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen

Just update the bootloader if you ever see news posted on the front page about "new bootloader; please update!".

thanks a bunch guys,
currantly I am running the latest bootloader and r13990-070726

Just a note:  this isn't the bootloader version, it's the Rockbox SVN revision number.  And you can get the revision number by selecting System --> Version rather than by rebooting.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: Llorean on August 03, 2007, 01:48:55 PM
Actually, it depends on what screen he got that, I'm pretty sure that aligns with one of our bootloader releases, and that one showed the SVN revision of the bootloader rather than a simple version number. So it could be his bootloader version.

If so, it's a ridiculously old bootloader and should be updated. :)

HAHA, thank you for the help guys, installing the new bootloader has fixed things so far (2-3hrs of use and no errors), so relax its updated  ;)
I even got a new theme that's much more legible while installed in my truck
you guys are all doing a great job, thanks

now back to tvg...how are things working out? are you just sticking with the older build?

14180 is OK! Thanks, developers!

And NOW in "Debug\Audio thread" there are visible switchings from 30 mhz to 80 mhz and back.

I'm having similar troubles again (as previously addressed in this thread (http://forums.rockbox.org/index.php?topic=11675.0)). I was using a over-a-year-old build and bootloader, and when I upgraded to current, pretty much everything went haywire. It might work flawlessly through the day, it might play but skip (like a broken mpeg stream skips) a LOT or it might just crash with a data abort or some other message when starting playback.

Anyway, I tried the official iPod firmware today (and upgraded to 1.3.1 :-[ ), which worked fine, playback and all, so I'm kind of starting to think that this isn't a hardware problem for me. I reinstalled Rockbox (with current build), and presto, codec errors and crashing. Once I managed to get it playing with the 20070726 build recommended earlier, but when I switched to another font (the one I've always used, nedore-9, with iCatcher), it started crashing again, exactly the same way as previously - it loads the background image for the theme and immediately crashes.

I don't know what to say... help? :'(

Edit: Interestingly, everything seems to be working right now. Running r13990.

Edit 2: Nope, still skipping.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: tvg on August 13, 2007, 08:34:46 AM
maraz, r13990 does not skip, really. You shoud better 'reinstall' it: delete .rockbox folder and install again, also try to reformat the ipod. 13990 plays well, i think.

Post by: Llorean on August 13, 2007, 09:32:16 AM
Just because it works well for you is no guarantee it works well for everyone. All of the revisions work well for me, but clearly they don't for most of you.

Suggesting someone reformat their iPod is almost always pointless, there should be very few (if any, ever) occasions where this is necessary.

hey guys...first time poster and at the risk of sounding like a complete noob I am having the same problems with this rockbox thing. I keep getting massive audio glitches from playback of mp3 files, and wma files either won't play, or will play for 20seconds then skip track and keep skipping tracks until i turn the thing off. I also get a lot of data abort errors and something about an instruction error? sorry but I dont know much about this stuff. The database is always recommitting itself and leaving out tracks and stuff. The funny thing is everything else works fine. Doom works fine and so do the demos and stuff...its just the playback that seems to be not working. I used the current build with the latest ipodpatcher...I dunno what the bootloader is so I just assume I have the latest one...I have changed back to my ipod software atm but I really digged the advance features of the rockbox like the eq and stuff...I want to get it working :(

Post by: webjockey on August 20, 2007, 09:43:53 AM
I would like to say that it also happens to me (I also have a 4GB iPod Nano 1st Gen about a year old)
Sinc I have no FLAC files, I cannot test them, but, the mp3s, the more compressed they are, the worse the playback, I am currently listening to a 192mp3 and it is doing pretty well, the glitches are very few, there is no skipping, and the time doesn't flux.
But, previously, I was playing a 249mp3 and the time was becoming faster and slower, there were frequent glitches etc. etc. No skipping though and I didn't get a data error (although, it is worth noting that I did infact geta data error for the very same song on a daily build, all the other songs work well) That was when I switched to the current build. All the songs start well, and sometimes, they play flawlessly, even the aforementioned 249mp3 (just to note its Animals - Nickelback, not that its necessary to know  ;D ) plays well. I just wanted to add my two cents, and it seems to me its the compression that is doing this. please comment, I really like Rockbox and don't really want to switch back  :-[

Just for the record, a 249kbps MP3 is *less* compressed, than a 192kbps one.

ah, i see...
hmmm, I just thought the more compressed it is, the more there is to uncompress, so the more difficult it would be for Rockbox...

and jsut to note, my music was playing absolutely fine, and then, I opened up Rockdoom while playing some music, and it gave me a data abort...
I thought, fine, don't play music and run rockdoom, so I go back to my songs, and now every single songs returns a data abort (each with a different hex number) I even tried to delete all the rockbox files and reinstall them, but nothings working....

Post by: Chronon on August 21, 2007, 05:55:30 PM
I just bought a 2GB nano from eBay and it seems to suffer from a similar problem.  MP3s seem to play fine.  But MP4 (aac) files play for a couple of seconds then playback skips to the next track or even skips several tracks.  I've tried re-booting and clearing settings.  But this certainly sounds like similar behavior to what the OP reported with FLAC.

I just installed from scratch using the rbutil, which should be using the most up-to-date bootloader.  

I'm running r14396M 070821 (I compiled it myself today, but the source was a couple of days old.  I will update my sources and try again.)  *compiling now*

*update* I'm now testing with r14416M 070821 -- though judging by the changes to the source I don't think I'll see any difference.

** I am indeed getting the same behavior.  Higher bitrate definitely seems to aggravate the problem.  I have some 128kbps AACs that I tried and it seems to skip on the first track starting at about the 1:36.  Each subsequent track plays for for a random time between 1 and 10 seconds before skipping to the next track.

In contrast I have a 256kbps AAC album.  It plays the first track up until 0:23.  Then it randomly skips some tracks, playing a random set of the remaining tracks for 1 or 2 seconds each, but ended up playing about 0:10 of the 9th track for some reason.

So, it seems to definitely perform the best right when playback has been initiated.

I'll play with it further.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: webjockey on August 22, 2007, 04:41:31 AM
Well, I solved the data abort problem witha system restore and fresh reinstall (I keep a Rockbox_Dump on my computer from when it was worknig fine, so that its easier to reinstall, but that didn't fix it, so  I unextracted everything anew and put it back on my computer after a system restore of the iPod)
I don't know, but, has anyone with the problem tried restoring their iPod, and then putting the music on, and then putting Launcher 2 (If you use it) and putting rockbox on the very last? Thats how I did it the first time, with my Rockbox_Dump, it worked fine, its just that now, when the only difference seems to be the order (and the lack of a Linux Partition) it has started to glitch.

So I am back to square 1 ...

Post by: Chronon on August 22, 2007, 01:49:02 PM
Well, I reverted to an earlier build to see if this player behaves similarly to tvg's.  I am currently running r13989 without any trouble.  All files play back smoothly with no hiccups.

By this time it's impossible to get lastworking version - ~~13990 - it is out of site.

May be it can be useful to roll-back the improvement, which led to such a unstable behavior? For a while, until the problem will be solved.

Post by: Llorean on September 04, 2007, 11:49:02 AM
Rockbox is not released. It would be best for people to continue working on it, instead of continually asking for versions that "work" so they can pretend like the problem doesn't exist. This problem WILL NOT get fixed if nobody who has the problem figures out exactly what the problem is, and if all of you keep wanting to go back to 13990, and simply pretend like the problem doesn't exist, it will be much, much, much longer until it is fixed, if ever.

Users who experience problems represent a feedback mechanism for the developers.  If they don't get feedback then it can take much longer to identify what changes to make.  

In that spirit, I'll keep testing new builds.  However, this nano is slated to become a gift for someone in a couple of weeks.  So, I only have a small amount of time left for testing.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: tvg on September 06, 2007, 12:43:58 AM
But noone now is notified that the last working build for his player could be 13990. And even if so, nobody can download it, as I assume.

And the very few can really improve the code, others can only use.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: mikelx215 on September 06, 2007, 07:22:27 AM
I agree. For the end user, the current builds could mislead someone into thinking that Rockbox is a buggy, unusable and unusable application. And if they were using a 1st gen nano that wasn't playing nice with the new Rockbox, they'd be right.

For the end user, who is code illiterate, several things need to happen. (This would be even more important if there will not be a fix in the near future.)

1: Since this is a serious bug (makes music unplayable, among other things) that appears to affect a sizable amount of your audience (including myself), there should be a notification somewhere on the main page or the build download page. When I updated Rockbox I had no way of knowing why it was constantly jumping to the next song.

2: As a temporary fix, a latest 'stable' build should be in the download section. For dumb end users who can't code, like myself, it'd be great if we could still use Rockbox while the current build is being fixed by the amazing and talented people who know what they're doing.

3: If you are unable to put an older binary (or the test 1 which works great) in the downloads, could I suggest a way to underclock Rockbox in the Settings menu? If possible, users with the bug could still use Rockbox, while providing feedback on the current build and still contribute to fixing the higher clockspeed problems.

Rockbox is a fine firmware replacement. I like it better than the iPod OS, if I didn't I wouldn't be using it.

But again you're assuming that Rockbox is a released product, which it's not.

Anyone using it is a tester, whether they like it or not.

How much testing can an end user do if the daily builds don't work for them? Not a lot.

When will the bug be fixed? From the looks of things it won't be anytime soon. How many people won't become contributing members of the Rockbox community, thinking Rockbox is a buggy unusable firmware replacement?

This is a pretty serious bug, as it breaks on of the main functions of Rockbox. Just a small notification could inform so many people.

If needed, someone could host a mirror of 'test 1'.

They can test each current build as it's released, and report on whether the problem has been fixed or not. That's how.

Post by: Chronon on September 06, 2007, 01:55:18 PM
Well, that doesn't seem entirely realistic, GodEater.  Probably they'll update periodically and report if the problem gets fixed.  This thread and the flyspray task would quickly get bloated if those of us with this problem reported this for each firmware revision.

I would advise keeping a backup of a firmware revision in which playback works.  Then update periodically to test.  If a new build works report it here and in this flyspray task (http://www.rockbox.org/tracker/task/7510?histring=nano%20playback%20skip).  In the event that it doesn't work you may revert back to the backup that does to enjoy your music.

We want to continue to test new builds so that we can provide feedback if any changes in the source fix what we are experiencing.  But it's totally understandable that people don't want to languish with an unusable DAP until the problem is resolved.

-------------
edit:
As a note, playback is still broken in recent revisions (e.g. r14627).  I'm reverting to a working build to listen to music.  I'll try again with a build tomorrow

In response to "How much testing can users do if the daily builds don't work for them?"
1) Users aren't supposed to use the daily anyway, they're supposed to use the current.
2) If the current doesn't work, not a lot. If they test a 600 revision old version, though, the testing doesn't mean anything, so it's useless to use for them to use that version either.

I understand that users don't want to have an unusable DAP until it's fixed, but the bug won't fix itself. If users choose to ignore it because "I can't do anything" it may very be a long time. I don't see very many people asking "What can I do to help?" or coming into the IRC channel, or saying "I've been learning about X in an attempt to help" but instead saying "I don't care if the bug gets fixed any time soon, I just want to play music."

If I could code, I'd help with the coding. I haven't learned the skills required to help in that capacity. Maybe I'll contribute to the Themes.

The 'I don't care if the bug gets fixed any time soon, I just want to play music.' is a legitimate response. People are going to spend time setting up Rockbox, only to find that it's broken. That's going to really suck for the people who are new to Rockbox and haven't yet joined the forums.

As someone who can't directly contribute to the code, I feel that it would be nice if a stable build were to be provided when the code gets buggy. It took way too much digging to find the last working revision. It would be helpful if access to older stable binaries were available.

PS: I'm not complaining, I'm suggesting something that I feel should be done in the meantime.

Again though, how does having users use a working version help move toward fixing the bug at all?

None of their testing means anything (it's days, weeks, months out of date) and it encourages them to NOT work on the problem.

I've said this several times: This problem does NOT happen on any developer Nanos, so it is highly likely that someone experiencing the problem will have to do a decent amount of work on this. This means that you should be saying "How can I learn to help" rather than "Please give me a build that works."

What happens after a non-developer does their part? They sit around for weeks or maybe months waiting for the problem to be solved, not using the features or codecs supported by Rockbox.

Having the end users who can't code playing around with a slightly outdated revision of rockbox can't do much more harm than them using an unusable firmware.

Now, if a message were posted somewhere near the download page that looked something like this..

Recent Rockbox builds for 1st Gen iPod Nano may have broken audio playback. If you are noticing that songs are changed frequently without user input and are getting Data Abort errors, please visit the forums.

There is no such thing as a non-developer, because there is no such thing, strictly speaking, as an "official" developer. There are people who spend time working on Rockbox because they choose to, and people who don't.

A notice could be posted to help direct people, but that page is out of my control. I do think though that it'd be better for people to actually *work* on it than to simply say "Oh, newer builds may have problems, I'll not update until they go away." Which is going to take longer: Someone who has the skill, but isn't working on the bug because they have nothing to work on, or someone who has the bug but doesn't have the skill so they start learning what is necessary?

I think you're making an artificial split between "Developers" and "Non-developers." The real line is, entirely, "People who are currently working on Rockbox" and "People who aren't" in the end. Anyone can choose to join the first group, but nobody is obligated to. But the second group really has no call to have any expectations from the first group, since they've chosen not to join it. While programming may seem like a big scary thing, it's entirely a mental task, and like most mental tasks can be conquered if you spend some time on it.

I don't want to come off like I'm expecting anything. For the price (free), getting the iPod to display a picture of an alternate music player is excellent value. I'm just thinking about the people who aren't going to code themselves.

Your opinion being "The problem doesn't need to be fixed, so long as people can use the old version?"

Why don't you volunteer to loan your device to a developer who's interested? The problem is not going to go away, but as is clear you and the people who are experiencing it seem to have no real desire to fix it, and just want to pretend like it's not there by going back to older builds.

The message seems to be this:

Developers can't very well work on something they can't see or test.  Either someone who experiences this problem needs to dedicate some time and effort into finding the source of this problem (be a developer) or they should offer to lend their player to a willing developer so that they will have something to test and work with.

That all sounds reasonable to me.

Not at all. My opinion is that while people who are contributing to the code are contributing to the code, the people who would like to be able to use Rockbox should be able to use Rockbox. But I can see that I'm starting to be disruptive to this thread.

I'd be happy to continue this conversation over personal messages, if you'd like.

Edit: I don't have another personal media player at the moment and iPods are fairly expensive. Since I'm a high school student and have a fairly limited income, I'd rather not ship an expensive product. Sorry.

I think the big point you're missing, in entirety, is that Rockbox is a project for developers. It was created to scratch an itch, and anything that gets changed or improved is done by someone that wants it to happen. Users are nice, but in my opinion at least, a little user inconvenience to encourage someone to actually work on this problem is not a big deal.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen

Fair enough. Rockbox is more than fair actually, it's a free Firmware replacement with a decent GUI. I appreciate the fact that the hundreds of people developing the software are doing this in their spare time of their own free will.

If I've upset you with my suggestion then I'd like to apologize.

I intended to suggest, not demand.

Post by: Llorean on September 06, 2007, 05:23:07 PM
I may have been harsher than usual too. I've been stressed outside the forums lately, and I already went off on one users.

But in all seriousness, in the current situation it's unlikely that the problem will be fixed soon. I'd rather inconvenience people for a little while in the hopes that someone will be inconvenienced enough to take one of the steps (work on it, or loan his player for an indeterminate period) than leave the problem in existence indefinitely. In the latter case a year from now people still may be using r13990 because everybody's just bumped into the bug, downloaded the older version, said "Well, I can listen to music again, no sense sending off my player, surely someone else will" and go on with their life.

I know it's a bit of a cynical way to look at things, but you can see how long the problem's already stood up. We've got one developer who's at least curious about the problem, and I and a few other developers with Nanos have tried various things to make the problem show up on ours with the full intent to mail it to him if the problem showed up, but it just doesn't happen on all players. This also means that buying used Nanos is unlikely to help, all signs show that at least it's a small percentage of the players (I would hazard less than half) or I think we'd be hearing a lot more about it. And even if it's more than half, finding one on the first purchase isn't necessarily likely.

Post by: Febs on September 06, 2007, 05:33:55 PM
I have to say, I agree with Chronon and mikelx215.   If we have a bug that is significant enough to actually prevent a user from playing music on a player that has in the past supported music playback in Rockbox, I think that users should be advised that they will experience this bug if they upgrade to a current build.  I don't see how it would hamper development or squashing of the bug to say to users:

"This build is known to have a bug that prevents music playback.  Please read this [link to FS task] for information on how you can help us to identify and fix this bug.  Otherwise, we recommend that you want until this issue is resolved before updating."

That is, after all, the basic message that people get when they ultimately find threads like this one after experiencing the problem.  I don't see any legitimate downside to conveying that same information to people before they experience the frustration of installing a non-working build.  A warning on the current build page would serve three purposes:  (1) it would clearly and distinctly advise people how they can best help to resolve the bug, (2) it will lessen the support load in these forums and on IRC, and (3) it will help ease end-user frustration and prevent people from forming a negative opinion about the stability of Rockbox.
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: Llorean on September 06, 2007, 05:39:45 PM
I think a notice like "Warning: Some users of iPod Nano may experience playback issues. Keep a backup of your old build before updating. If you are one of these users, Rockbox needs YOUR help, see FS####" might be okay.

But I really do fear that without some sort of stronger encouragement to help, it will be a very, very long time before this is fixed. The problem I have is with the idea that an explicitly "working" build should be made available, as that suggests it's "Rockbox without the bug." We've already had one person file a bug report on a 700 revision old build, and I'm almost sure he knew better anyway.

I know this was referred to before, but I think one of the biggest problems that we have is that we get a lot of users that just don't care about what we do or what Rockbox is about. There seem to be a lot of kids coming in to use Rockbox just to show off Doom and Game Boy games on their iPods to their friends, and personally don't give a rat's ass about the developers or what we do to improve the project.

This was also mentioned before as well: few of the many iPod users are also developers, or even have programming experience. But to hell with that. I'm learning C again because I want to contribute something back. Rockbox freed my iPod from its restraints. I've got Vorbis playback. I've got FLAC playback. I've got some games to fiddle with. But best of all, I've got an open source project that's fun to tinker with, and to learn from! I even picked up my Archos to help further test the project. I'm looking to help start a new port for another device: the Dell Digital Jukebox. To me, this project means a LOT, and I want to help these guys out in any way, shape, or style that I can.

Every day that I use the iPod video (for 30GB) build means that I'm doing my part by testing SVN builds. So far, every single build that I've used since December 28th, 2006 have been quite solid and stable. Sure, there's the occasional hiccup or two, but they have solutions already. My Archos has been as solid as a tank since day one with Rockbox.

If these guys ever need help with finding bugs, testing SVN builds, or information for new ports, I'm here to help them out. I'm part of this community, and I want to do my bit for it!

I had been planning to give this nano to someone as a gift in a couple of weeks.  But perhaps I can make other arrangements and send this one to that interested developer.  
Title: Re: Faulty playback on Ipod Nano 4Gb 1st Gen
Post by: Llorean on September 06, 2007, 10:20:01 PM
Honestly, the instant there's a problematic Nano in the hands of Amiconn or whichever other developer takes an interest, I'll be all for posting a giant sign saying "NANO USERS: The current build is unusable for day to day use on many Nanos. If yours experiences strange bugs, please use this build (a link to one made from 13990, or one with the changes to circumvent the problem) but do not file any bug reports for other problems the build may have, as it is outdated code."

I'd just rather have people see clearly that this is a problem, and it needs to get solved, rather than just look away and cover their ears and hope, which is what it feels like they want to do. People are willing to give you output from the debug screen, but as soon as you mention that someone needs to actually work on it, the response is "Well, I'd rather just go back to an old build and let someone else do it."

I know it's a bit cynical, but we've all seen issues sit around for incredible amounts of time without anyone having the time or ability to look at it, and while this one is more serious than most, it's also a case where at the moment there's not really a likelihood that developer *can* fix it if the current situation holds.

The possibility still remains that a developer can study how the Apple firmware initializes things and learn what's necessary from that, but it may also be that nothing useful is learned, or that after something is learned it will need testing, and tweaking, for some time, which will again require almost immediate access to a problematic Nano.

I want to see your Nanos playing music more than anyone, but I want that to be because Rockbox is capable of it again.

Surely any Nano shipped off to an interested developer will be returned once things are fixed, and I'm almost as certain arrangements can even be made to cover shipping, the problems are simply that
1) We need someone with a problematic Nano willing to part with it (we have plenty of people willing to part with Nanos, but they all seem to work fine)
2) We need a developer to agree to receive said Nano and investigate. I think the most likely bet for this is Amiconn, as I've said, but I don't want to sound like I'm volunteering him for it, just that he seems to have taken some interest already.

The best thing to do if you're one of the people with a Nano and are willing to consider it is to go to the IRC channel, and talk with the people there.

If I had a nano that was having this issue, I'd glad donate it in the name of bug fixes. Unfortunately, it's just me, my iPod video, and my Archos JBR v1...

Just to add my 2 cents. R13990 cures the "problem" for me. And to quickly see (literally) if there's the problem in a given revision, load a video with mpegplayer : it starts Ok but a few seconds later, colored or noisy blocks are randomly visible and sound has the symptoms described earlier in the post.

Are you claiming that the current build causes the Apple firmware to transfer more slowly via USB?  Apple's emergency Disk Mode launched from flash ROM (what Rockbox currently uses for USB transfer) is known to be much slower than the USB connection established through the firmware.  I just want to be clear on what you're saying.

Thank you x 10!  :) This really saved my vacation - I updated to a post 13990 build before I left on my vacation. Luckily, our second hotel has internet, and I found this thread and this download link.

I also have a 1st gen 4GB iPod Nano (bought pretty early on) and with all post 13990 builds (downloaded after July 30, 2007)  there's terrible skipping and glitching when playing mp3's. As others have pointed out, it seems that higher bitrate tunes are more prone to causing this. After a few minutes your tunes sound like lo fi, low bit-rate rubbish!

For people with an affected iPod Nano, currently there are no working Rockbox builds online (save the 13990 one, which is well hidden in the forums).

Until this is solved, there ought to be a little notice about this on the current build page. Otherwise people with affected iPods will turn away from Rockbox.

Is there anything I can do to help tracking this down? I really want to be able to get the goodies in the newer Rockbox builds...  :(

Oh, it is? How/where do you acess that? I've only found files from 2 months back on rockbox.org. That "svn link" should be posted here if the link above should get deprecated.

With "being online" I meant: (and from your quotation marks I believe you got it) reasonably easy to find for the average visitor. I consider myself pretty knowledgeable when it comes to computers & the internet (I work with IT), so I would think a lot of people can't find it either.

I'd say this bug is very serious ("showstopper"), but of course I don't know how many iPods Nanos that are affected.

Hm, but how about isolating and inspecting the changes in the audio playback routine between the last working build 13990 and the next?

The glitches sound something like, in 1995-1996, when you downloaded mp3-files as the wrong type (binary/ascii) with Netscape Navigator and had to run the "uncook.exe" file to get them fixed. :)

The problem isn't due to a change in the playback code. It's currently believed to be a timing issue brought to light by finally using the iPod at its rated speed rather than slower.

The build linked by TVG simply undoes the increase in speed, but some people have reported these problems even on Nanos running at the slower speed. It appears to be some sort of hardware difference.

As I've said many times, this problem isn't going to be fixed until someone works out what exactly is being done wrong, but people seem to enjoy making a lot of speculation (see all the speculation about overheating, for example, where they still haven't proved precisely that it overheats, just that current code runs less stable 'hot' which is not the same thing as nobody's actually checked the temperatures it's at with old and current code, but seems to be to them).

It seems this version works!
(taken from http://www.rockbox.org/tracker/task/7510 , scroll down).

Yes, it works! ;D I've been using it for a few days and Rockbox is just like it used to be!

Is it advanced to modify new builds the way the above was? Can one just apply a simple patch or do you need to be versed in compiling and such to do it?

A patch is a change to the source code, and you then compile the modified source.

http://www.rockbox.org/twiki/bin/view/Main/SimpleGuideToCompiling is the newbie's guide.

At first it may look daunting, but it's quite easy if you read and follow the instructions.

Ok, thanks for pointing me to the info!

*sigh* I hope the problem will be solved / the Mhz change rolled back in the main builds soon. :-P

As has been pointed out *many* times, the change isn't going to be reverted, and until someone with a problem Nano either fixes it or lends it to a dev to work on, it isn't likely to get fixed.

Especially considering the fact that some people have reported still experiencing the problem even with the mhz rolled back to 78 (or even 75 if some of the reports are accurate) meaning you're still in the same situation: "The problem is here, and it affects some people but not all."

Exactly. I hope this gets a solution soon!

Yes, that is very weird if Rockbox used to work for those people. Non consistent behaviour is very unfortunate!
