This problem seems to concide with the following error message in the kernel log: hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
Do you have any idea what could be the cause and how to debug this issue further?
First off, try the very latest alsa-driver snapshot. 2.6.29 is already very old, and there have been bunch of fixes and improvements since then.
Also, load the driver with model=auto option, too.
If both don't help, please attach alsa-info.sh output (run with --no-upload option) to analyze more.
OK, I've upgraded to kernel 2.6.30, then installed the alsa-driver-20090923 snapshot (configured with --with-debug=full).
I'm also running with the following options: bdl_pos_adj=32 probe_mask=1 model=auto
I'm attaching output from alsa-info.sh just in case.
If the problem reappears, I'll let you know.
If it doesn't, then I'll try running without any snd-hda-intel options whatsoever, using only defaults.
