[vdr] no sound with nova-t and dxr3

Hell alltogether,

I'm trying to get vdr 1.3.31 on debian sarge (mixed setup with some 
testing debs) at work. Video is running fine, but audio is still a problem.

I use a Nova-T (DVB-T) budget card with a dxr3 mpeg encoder card.

Maybe the reason for my sound problems could be with ffmpeg, cause some 
google findings sound like, but I'm not really sure.

Starting /etc/init.d/vdr, syslog tells me:

...
Oct 22 15:27:48 linux kernel: em8300_audio.o: Analog audio enabled
Oct 22 15:27:48 linux kernel: em8300: Microcode version 0x29 loaded

Oct 22 15:27:48 linux vdr[6915]: dxr3: intf:

Oct 22 15:27:48 linux vdr[6915]: dxr3: ffmpeg: codec 0x15000 not found - 
not supported by FFmpeg?
Oct 22 15:27:48 linux vdr[6945]: DXR3 audio output thread started 
(pid=6945, tid=49156)
Oct 22 15:27:48 linux vdr[6915]: dxr3: ffmpeg: codec 0x15000 not found - 
not supported by FFmpeg?

I didn't find this dxr3: ffmpeg error via google, thus I only guess that 
this could have to do with my audio problems.

I have installed
ii  ffmpeg                    20051016-0.1
which looks quite new for me.

The dxr3-plugins' Makefile expects ffmpeg files here:
-rw-r--r--  1 root staff 73042 Oct 16 13:51 
/usr/local/include/ffmpeg/avcodec.h

so for me they seem to match.

I have no idea what to do to get audio working, any suggestions?

Furthermore I tried things like bitstreamout, which I couldn't get 
working too.

Another possibility might be to get rid of the dxr3, put the video over 
my Geforce 6600 (it has an built in mpeg decoder, but I don't know if 
one could get this working with vdr - maybe with the softmpeg-plugin?) 
and redirect the sound via my onboard-sound-system (but how could that 
be achieved?)?

BTW, DVB-T itself is working fine with kde's kaffeine, with video _and_ 
audio - there's just some delay of a second or so between the video and 
the audio which I can't get rid of. I use the xine-dxr3-plugin with 
that, it's working fine.

If I only could get this setup for vdr!

Any help is very appreciated,
TIA and kind regards,
Andre
