On which model of player is this happening and how old is your rockbox build (and is it an official build)?

Sorry... it's h120, 20061012, daily build.

Works fine here with current CVS (20061115) on a h340 (which should be almost identical in terms of code)

I used STOP, not pause...

Can you check again please?

bug to be closed if OP doesn't confirm

It's entirely convievable for the buffer to get out of phase by 2 bytes which would reverse channels. Will investigate asap.

I'm sitting here trying to do it with a test file and cannot.

I have had a similar experience with my r13390-070726 on my ipod Nano 1st gen. I was playing two similar files different encoding, classical piece Pachelbel's Canon in D, one was an mp3 and one was a FLAC file. I was doing a blind test to compare my VBR encoding and some reason one time I noticed that the that the audio channels were reversed so I took off my headphones and checked (it was impossible too because the cable is only on the left side). I then went to the channel settings and found something really weird, if I go to stereo the channels seem reversed... I then go to Mono Right and I hear the correct right, and Mono Left and I hear the correct left but when I go to stereo, what I heard on Mono Right was on left and Mono Left on right, hence reversed. This happened after I pressed next a few times with only those 2 tracks to mix which one I wanted to hear. I then stopped the music and restarted one of the files and the channels are correct again. I'll post again when I have reproduced the issue.

I cannot use any newer build for my nano because they are currently broken.

Is this still an issue?
