Faulty playback on Ipod Nano 4Gb 1st Gen

[lanfear]

Well, that depends on what you mean by "online".  It is still quite accessible from svn.

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.

The process for retrieving file from svn is very well documented in the wiki - just go look there for it.

Thanks!

Anyway, the real point is - can somebody please put a note about this on the current build-page for the iPod Nano 1st gen. We don't want to scare away any potential Rockbox users or updating old users, right? The short blurb could include info about going to the wiki to read about how svn works to get a working build from there.

Is there anything I can do (submitting debug info etc.) to help track this down (besides the already mentioned iPod donation)?

I think it's going to require someone with the skills to have a unit in front of them to work on.  Either a developer can obtain a buggy unit from somewhere or someone with a buggy unit can put the work in and isolate what is causing this.

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.

It seems this version works!

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).

Yes, it works! 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?

[yapper]

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.

[Llorean]

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!
