Sansa e280, daily build from 1/28/2009

On a very small number of my MP3 files, playback at the start of the song will stop and start a few times, usually 3 times, and occasionally crash the player. The playback will start normally, and after about 3 seconds will stop for about 5 seconds, and repeat this 3 times. These files weren't ripped by me, but they appear to be normal Lame type rips, and play in other players fine. I tried attaching one of the files that does this, but it's too big - download it here - - Time.mp3

This task depends upon

That file has a huge ID3v2 tag at the beginning. Does removing that tag make it play properly?

No. There is an image in that header - I tried first just removing the image, and then completely removing the ID3v2 tag, but the behavior was as before - no change. I also tried this the last time I had this happen, back in December, with the same results.

I've uploaded a version of the same file without the embedded image if it will help -
this version still does the stuttering thing.

i would like to note: I have been having somewhat the same issues for a while now, what type of crash are you seeing, is it a data abort, or does it just freeze and die? mines a data abort on my e250s always at the location of 000090D0 (0). this still happens occasionally with my media files... but like you, only a few, and i encode with lame

My behavior is as described above. On the odd times that it crashes, I don't get an error message - the info on the wps just goes blank and the unit freezes. It's probably some kind of encoder setting that doing this - it's just certain groups of files, not ripped by me, that do this.

I have never been able to reproduce this on a 5G iPod. I don't know why it would only happen on an e200 series Sansa.
If you get a data abort or any other kind of error message which gives the address please report the address and post .rockbox/rockbox.mi4 so it is possible to find what instruction is causing the problem. The address depends on the particular build because things can move around between builds.

I don't know about ipods - there's a quite a few differences in the hardware and software involved, so different results would be expected.

And as I've noted before, I don't get an error message of any kind, just the behavior as noted.

I should mention that I haven't tried this file recently on any newer builds - it's sort of become a non-issue for me, and as I can't get anyone else interested in taking a look at it, if someone wants to close this, that's fine with me.

Just tried this on a recent build - no problems on playback - issue resolved as far as I'm concerned.
