So here is the report :

1) The file which affects the playback is

2) I tried to remove only


3) I tried to remove only
entry-> = snd_pcm_substream_proc_status_read

4) I tried to remove irq calls, substream proc calls and
proc_status_entry calls

And it still doesn't work but...

pcm.c from my 2.6.2-rc1 and pcm.c from my 2.6.0 are the same...
Or on my 2.6.0 the sound works without any problem...

I use the same elevator "deadline".

I've Preempt enabled on both...

I'll maybe try the standalone version of alsa-drivers with 2.6.2-rc1...
Btw I'll try the 2.6.2-rc2 kernel before.
