No Sound, No UIRT?

[jtrahan]

running latest gbpvr with PVR 350 card. Sound, UIRT channel changing, recordings, everything works great, except for video playback. I know this is due to the PVR 350.

If I add a Matrox Parhelia card, and change GB to playback using software, playback is great, and GB never hangs. But, I have no sound, and cannot change channels? The channels change on screen, but UIRT never sends signal to my cable box. If I switch GB back to PVR 350 card, it all works again. I've tried changing audio cable between the PVR 350 and my sound card, but no luck.

Thanks for any help.
