Hi,
After search on https://bugtrack.alsa-project.org/ for CMI9761, I found
3 issues, all resolved !
The most similar is "ASRock k7vt4a+ with CMedia CMI9761 no mixer!", I
have one ASRock P4VT8+ with CMedia CMI9761.
Try boot with pci=noacpi (that put the interrupts on XT-PIC) but is not
one ACPI problem, because sound have same behavior with a normal boot.
After play around with alsamixer,
I got sound when unmute PCM and Off (mute) IEC958 Capture Monitor.
All others controls does change anything include mute or unmute the
Master.
Except VIA DXS (this one can do sound balance, left and right).
VIA DXS 1, VIA DXS 2 and VIA DXS 3 also doesn't do nothing.
Play around with
options snd-via82xx dxs_support
on file /etc/modprobe.conf
only with "options snd-via82xx dxs_support=2" I see any difference but
for worst, make disappear VIA DXS, VIA DXS 1, VIA DXS 2 and VIA DXS 3
controls.
Sorry for my weak English, if you don't understand something just ask
me, that I will try explain again.
