A few days ago the left audio channel of my sansa e280v1 died and I don't think I can repair it. So I've ordered a clip+. In the meantime I've changed the channel configuration to mono to listen to some podcasts.
I've configured my player to 200% playback speed, bookmark on stop and rewind 2 sec on resume (because of FS12167) and channel configuration mono.
At least with r30205, but I think the problem exists for some time, when I boot the player and start playback using a bookmark the output is garbled. Sometimes it clips, sometimes there is a reverb effect (bath room).
Reselecting mono or starting a new file resolves the effect. When reselecting the bookmark before reboot the effect restarts.
This task depends upon

I can't reproduce this effect on my new clip+ (r30221)

I don't know exactly what I did, but with r30267 I could reproduce this bug with my clip+ two times.

I suspect that this problem was fixed with the recent DSP rewrite that removed some of the nasty assumptions in the pitch correction code. Can you still reproduce it?

Both Problems seem to be gone.
