Hello,
Yesterday I posted this bug in the bugtracker:
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3013I have received no reponse yet.
I'd like to cooperate on solving this.
Most of such problems are caused by buggy BIOS, as the driver tries to set up based on BIOS information if the device is unknown.
Did you try to pass model options for ALC882? For example, model=3stack or model=6stack. Also, position_fix option is worth try to fix some playback problems.
Okay, so based on the 2.6.21-rc6 codebase:
position_fix=1 fixed the clicks.
BTW I had no success with any of the provided preset models - they were less correct than the auto mode (e.g. no rear with 6stack-dig).
OK, that's somewhat expected.
I also noticed that in the patch I accidently implemented position_fix=2, but it seems to work okay too.
Interesting. As default, the driver behaves as same as position_fix=2 (using a position-buffer), but with an additional check of validity. Then it falls back to position_fix=1.
Maybe the validity check doesn't work well in your case. Or, it happens in some rare condition.
