A weird artifact.

When I listen to some track on Clip Zip, it sometimes changes it’s speed (speeds up, without changing pitch) for one second.

It happens only once in each track.

It always happens randomly, so I can’t record a sample of it.

It isn’t problem with my files because when I listen to them on my computer, everything is okay.

I encode music in OGG format at ~208kbps VBR.

Why is this happening? How to fix it?

BTW: Sometimes in middle of listening to some track, player mysteriously skips to next one (but this skipping happens only with FLAC files). May this be related to this problem?

I installed latest rockbox dev build from yesterday.

Haven’t noticed speed issue so far…

EDIT: It just glitched :frowning:

I went back to original sansa firmware and this doesn’t happen anymore.
Probably just a rockbox bug.

This never happens to me on the stable release build. No way would I go back to the original firmware on my two Zips…

I don’t like original firmware too, but it doesn’t have glitches on my Zip.

BTW: I tried using stable build, but it was glitching too.

I’ll try compiling rockbox from latest source.

I compiled latest rockbox and installed it, but issue still happens.
How to reset rockbox settings and start over?

Edit: Nevermind, I removed .rockbox and installed it again.

Let’s see if problem persists.

Yes, glitches still happen.

These may be ogg/flac issues–haven’t seen this with mp3’s.

They don’t happen with MP3’s, but I don’t like MP3 format (Formats such as AAC or OGG can achieve same (or better) quality at lower file size).
