Please run with --no-upload and included the result in the post.
Done, output included in this e-mail.
Anyway, this problem might be related with the volume-knob. Install hda-verb and try the following
hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0xff or hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0
Unfortunately none of those make a difference.
After doing this, check /proc/asound/card0/codec* whether this node 0x28 is really changed.
Yes it does (the range is 0x00-0x7f and not 0x00-0xff).
The bit 7 is to specify the direct mode. Maybe we need to select the input of the widget beforehand:
% hda-verb /dev/snd/hwC0D0 0x28 SET_CONN 1 % hda-verb /dev/snd/hwC0D0 0x28 SET_VOLUME_KNOB 0xff
I'm afraid it doesn't make any difference either.
Did you check proc output and see any difference at all?
