This points to an audio playback issue, rather than a problem with the
capture card movement (in DVB the audio is embedded in the signal, on
the PVR-150 it's embedded in the MPEG-2 stream leaving the card).

You *really* need to see whether your system audio works outside of
MythTV, and if successful, proceed to testing in mythfrontend
(recordings/mythmusic/mythvideo).

Check your mixer settings on the machine, check your ALSA devices in
mythfrontend etc, check calbing etc. You might also want to check for
an IRQ conflict involving the sound card. It wouldn't be the first
time that something may have become unplugged /unseated during a card
redeployment.
