Thanks for taking the time to explain, it's now a lot clearer to me what
the whole stuff is about.

It happens you were right. My soundsystem was somehow b0rked. I tried
activating the internal soundcard and it gave me nothing too. There was
a distinct lack of /dev/snd/pcmC* without which alsa-lib couldn't work.

It seemed that I loaded the em8300 module too early (even before snd-*),
so after fixing that it works now!

I can hear sound through the digital output with alsaplayer -o alsa -i
text -d iec958 :) and the vdr-plugin-dxr3 works too, so I guess you did
all the em8300 stuff right. Great work!


cheers
