Summary: NVidia CK804 - Realtek ALC850 rev 0 - passthrough
not working
Description:

SPSA in 0x2a is set to 0, i.e. assigned to slots 3/4. This is basically
changed via "AC97-SPSA" mixer control. Change it to "3" (the highest)
manually.
Also, try to output the audio PCM signal over SPDIF with
% aplay -Dplug:spdif somefile.wav

Using xine I got a funny effect with SPSA:
Before starting xine I set SPSA to 3:
cat /proc/asound/card0/codec97#0/ac97#0-0+regs |grep 0:2a
0:2a = 05f4
After I started xine SPSA is set back to 0:
cat /proc/asound/card0/codec97#0/ac97#0-0+regs |grep 0:2a
0:2a = 05c4
What's going on here?
I tried to play a wave file but I heared no sound.
aplay -Dplug:spdif some-sound.wav
Playing WAVE 'some-sound.wav' : Signed 16 bit Little Endian, Rate 48000
Hz, Channels 6
<silence>
During this test I had the same funny effect of switching SPSA from 3 to 0
and back to 3. Is that normal? What exactly are these "AC-LINK slots"?
Channels on SPDIF?
