Uwe I was just cruising the mythtv-user mailing list and found a tale
much like yours in terms of audio on a PVR-500 card (a PVR-500 is
essentially two PVR-150's on one card)

The whole 9 yards is here:

http://www.gossamer-threads.com/lists/mythtv/users/204597

But to cut a long thread short there was a firmware problem. The PVR
150/500 needs to load two lots of firmware, one for the audio and the
other for video. It may be that your audio firmware is not being loaded.

Very carefully check your dmesg for errors involving the firmware for
any of the ivtv related modules.

FYI here is the IVTV dmesg log for my card, I have marked the relevant
lines ********
