Try updating to the latest ivtv driver (0.4.2).  There
was previously some issues with DMA which were causing
sound from recordings made on PVR-350 cards to lose
sound.  The most obvious way to see if that is the
cause is that you can't even try to change the volume
in MythTV (pressing Vol+/Vol- go completely ignored) -
at least that's the symptom I saw.

Otherwise, make sure you have the latest firmware and
that MythTV is properly configured for your cards
(there was a change in ivtv 0.4.1 or 0.4.2 that
changed the names/numbers of the inputs - when I
upgraded, I had to re-run mythtv-setup).

It can work, because I have the same setup (PVR-350
and PVR-500), and with ivtv 0.4.2 everything is
working fine.
