Tried that, but still doesn't work. I have set max audio channel to stereo 
then i get digital audio. it seems that "mp2 2ch" doesn't work, but "liba52 
2ch" works, but i have to switch audio tracks a few times until it works. 
Btw. .asoundrc is deactivated now. Makes no difference so far.

Can you plz compare my settings with yours?
ALSA:default
ALSA:iec958:{AES0 0x02}
stereo
active linear
AC3: yes
DTS: yes
aggressive: no
intern: yes
ALSA:default
Master

Thanks,
Flo
