[mythtv-users] No audio in live TV and corrupted recordings with second SAA7134 card.

[Thom Paine]

I'm getting no audio on my set up too. But my machine is a PVR-350 as the
main card and a PVR-250 as the seconday card.
No audio from live tv or from rcordings. Although my recordings are
suffering from broken video.
