Hi,
I have a two PVR-500 cards with their daughter cards attached. I am
feeding audio on the the line-in of these 4 devices along with
composite video input. The main cards work fine, however the sound on
the daughter cards is very noisy and unusable.
The system is running gentoo using kernel 3.10.7. Is there way to get
usable audio out from the daughter cards?
