I'd like to second that, but for me looping occurs at the beginning of
level.

True.

True.

Ture.

Same thing here.

alsa-0.9rc7, Debian unstable, kernel 2.4.20 on Toshiba Satellite 5105-S907
with Yamaha sound on board
(00:1f.5 Multimedia audio controller: Intel Corp. 82801CA/CAM AC'97 Audio (rev 02))

True.

I have made checks suggested in this thread. Results are the same:
interrupts are being generated and sttuses in /proc/asound keep changing.

I'm eager to help debug this. I know how to use debugger/compiler/whatever
it takes, I just need a push in the right direction.
