I think cx88_alsa is already loaded but I only get the one /dev/dsp device

I have an HVR3000, which sounds kind of similar, but it is 
analog/DVB-T/DVB-S.  To get audio from the analog part of the card, you 
need to have the cx88_alsa module loaded.  This gives you an extra 
/dev/dspX device.  Then you just configure this as the audio source in 
MythTv.

If you are using something like XawTv to test, you need to run arecord 
{ars} > aplay to get sound to work in a terminal window.

Robert.
