Well, I received my new audio receiver for my cinema room.
So the first thing I did was installed the GT220 card in the PC
(identical one to my other machine)..
Started.. and ... no sound
I've finally tracked the issue.
Following the steps I had written on how to achieve judder-free
playback, I had totally overridden the EDID with Option "UseEDID"
Well, this is what caused no sound for me.
I replaced it with:
Option "UseEDIDFreqs" "FALSE"
Option "UseEDIDDpi" "FALSE"
Option "ModeValidation" "NoEdidModes"
(which according to nvidia is the same), and I get audio ...
I guess UseEDID disables audio over hdmi as the nvidia drivers aren't
able to check if the display supports sound.
(note that without Option "ExactModeTimingsDVI" "True" , one of my
custom modelines were working)
I thought you could be having the same issue
