[maverick] Audio: spdif output

[Gerardo]

On Lucid, my sound card was able to output simultaneously to the desktop 
speakers and the spdif output.  I did a 10.10 clean install and now I 
can't do it anymore.  All audio output only goes to the desktop speakers 
only.  If I do

mplayer sample.ogg -ao alsa:device=spdif

the audio correctly goes to the spdif (but not the desktop speakers), so 
it's not a hardware problem.  I tried changing all the values at 
alsamixer, but it didn't help.  I tried removing pulseaudio, and still 
no luck.  Any ideas?
