[vdr] No audio output from DVB card, what to try next?

[Lasse Heikkila <racc@modeemi.fi>]

I've spent 5 evenings trying to get some kind of audio output from my new
Siemens DVB-C (rev 1.5) card. At least the analog outputs seem to be silent
and I don't have any gear with digital input to test that. I'm starting to
suspect the card might be defective, but it's a bit difficult to return it
because I bought it from another country. Otherwise it works perfectly, and
sound comes nicely from sound card when I play .vdrs with mplayer.

Any ideas what could be the problem? Vdr version is 1.2.5 and dvb 1.0.1.
DVB modules ves1820, dvb-core and dvb-ttpci are loaded.

I've tried to send audio to mplayer with -a switch, no luck. Also tried
ac3dec. In fact, it seems like vdr isn't sending any audio data to stdin
at all, I tried to give it to tee (vdr --audio='tee audiofile') but
didn't get any file as result. Am I doing something completely wrong?

The only way that gave any kind of live audio output is when I directed
data from dvb device to mplayer. Sound was bad and lasted only a couple of
seconds, but well, my best effort.

Isn't there any simple way to do the audio playback with a sound card? Any
things to check from kernel (2.4.22), dvb or vdr? All suggestions are
welcome, I've run out of ideas. Almost any kind of solution that would provide
analog stereo output is ok.
