Absolutely no playback under Rockbox

[brownbox]

Hi
I am the proud owner of a Sansa E250 with a 2gig micro SD card installed.

I installed rockbox today, and got it all working great (doom is awesome!   ). Anyways, its all working fine and I have a theme loaded up and all my settings changed. Problem is when I go to play any file (all mp3's) it doesnt play it. It just stays at 0.00/x.xx. Then the whole system gets really slow and laggy, and the only way to make it back to normal is to reboot. The files definately play in the default Sansa firmware. Sorry I cant really provide much detail, and I am new to all this, however I will try to answer any questions.

Cheers
BB

P.s. Nice work overall with Rockbox. It really does ... rock...

Are these files you've purchased on line at all? I.e. with DRM ?

[brownbox]

these files were ripped these off a CD (128kbit mp3 format)

also sorry about posting in the wrong place

Could you do what you're asked to do when you post then please?

Provide the svn revision number of your build?
And also - make sure the problem occurs when all the settings on your sansa at their defaults.

[brownbox]

As far as I know none of the files have DRM

The version number is r15276-071023

I completely wiped Rockbox and reinstalled it, and it still has the problem.

[brownbox]

Alright, I had a little play around with it.

it plays maybe 1 second of the song, then skips to the next one. It just keeps going like this through all the songs.

What did you do to "completely wipe" it ?

[brownbox]

I entered recovery mode on the player, and did a full reformat and firmware flash then reinstalled.

[GodEater]

I'm not massively familiar with this player, so I'm unable to comment on what this does in terms of a wipe.

Could you just delete your .rockbox directory and all it's content, unzip a fresh build onto your player, and make sure you don't change ANY settings (no theme, no sound settings - nothing!) before you attempt to playback your files.

Actually, it can be a problem with the MP3 files. Each frame in a file can contain a CRC value, and some encoders put an incorrect value there (rather than omitting it). Some decoders check this value, and refuse to play the frame if the CRC is incorrect. Rockbox does currently check the CRC (though it can easily be changed), which could explain this behavior.

I think mp3check can check for this. There may be other programs that can do it too, but I'm not aware of any.

[brownbox]

Lear you were spot on. I scanned a mp3 file with mp3check and now its playing flawlessly on my player!  

One last question
Do I have to do this to all my mp3 files?
Does this also apply to wma files?

[Lear]

All MP3:s with bad CRC, yes.

WMA is not affected by this.

[brownbox]

well Im afraid to say I still have a problem.

Its one particular file which plays fine everywhere else (orig firmware, windows, etc)
I can encode it to mp3, wma or ogg @128kbps. I check it with mp3check and it comes up with no errors. However, when I go to play the file in rockbox, I get
No File!

(root)


Whats the problem here?

[GodEater]

Can you run a chkdsk/fsck on your sansa when it's mounted ? In case you have filesystem errors.

[Lear]

If checking the disk doesn't help, I could take a look at the file. In that case, PM me.
