Hello,
Since 2.6.34-rc*, I have a regression on alsa which prevents the sound to be played correctly. When playing, the music goes too fast, skipping some parts. Typically, it's very easy to reproduce by doing: time mplayer -endpos 30 sound-file-which-lasts-more-than-thirty-sec.mp3
If the wall clock is less than 30s, you have the bug. With my intel-hda (AD1981), it's reliably reproducible: it gives ~27s, instead of the normal ~31s.
After bisection, it turns out that it is commit 7b3a177b0d4f92b3431b8dca777313a07533a710, aka "ALSA: pcm_lib: fix "something must be really wrong" condition" which caused this regression. Reverting it on top of 2.6.34-rc3+ fixes the problem.
What happens if you pass position_fix=1 option to snd-hda-intel? Is it via PulseAudio or other backend?
thanks,
Takashi
