Still wondering why setting AC97-SPSA to 0 doesn't work in this case. Try the following:
- plug to the analog output on docking station
- set "IEC958 Playback AC97-SPSA" to zero via alsamixer or whatever
- set "IEC958 Playback Switch" on
- run % aplay -Ddefault foo.wav
| aplay -Ddefault shutdown.wav Playing WAVE 'shutdown.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
-> Silence
| aplay -Dspdif startup.wav aplay: main:550: audio open error: Device or resource busy
-> I got the totem player open in the background, it didn't produce any sounds but seems to lock the pcm channel.
After closing totem player:
| arcs@storm:/usr/share/sounds$ aplay -Dspdif startup.wav Playing WAVE 'startup.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
-> played sound
| aplay -Ddefault startup.wav Playing WAVE 'startup.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
-> still no sound
hoped that helped.
cheers, Andreas
