The video4linux mailing list is a more appropriate venue for this 
question (cc added)

DMA audio over the PCI bus is not yet supported by the cx88 driver -- 
it's currently being worked on.  If you card has an analog audio out 
connector, then you'll have to connect it to your soundboard in order to 
hear analog audio.  I don't think the HVR1100 has analog audio out -- 
not sure about that one, sorry.

Well, that's interesting.....  I can't explain what that message above 
means, maybe someone on the v4l list would care to dive in?

Regardless, analog audio will not work on cx88 cards yet without an 
audio cable connected to the sound board.

Give it a few months (i hope)...
