No HDMI audio from new Gigabyte (NVIDIA) GT220 graphics card
Hello all! I searched and found similar (but not close enough) problems.
Specs up front:
W7 Home Premium x64
Asus M2A-VM motherboard
AMD Athlon x64 5000+
4GB RAM
Gigabyte GV-N220OC-1GI GeForce GT 220
On-board audio (aside from the HDMI out on the GT220)
I have an LCD monitor I use 98% of the time on the DVI plug and an HP projector for watching videos hooked up to the VGA plug. I bought this GT220 specifically for the HDMI audio out to my receiver.
Except the HDMI audio doesn't work, whether or not I disable the on-board audio in BIOS. I downloaded the latest NVIDIA drivers (July '11) and the computer recognizes the receiver.
If I start playback, you get the little bars dancing next to the receiver in audio properties (See image below) but no sound.
Unlike older cards with HDMI plugs, this one has no SPDIF inputs; should get all the signal through the PCIe bus... I guess...
It seems Windows is smart enough to disable the on-board when I turn the receiver on, and re-enable it when I turn the receiver off, but not to actually send audio to the receiver.
I know the receiver & cable are good because if I unplug the cable from the computer and plug it into my WDTV I get HDMI audio... but when the cable is plugged up to the computer, "HDMI" doesn't appear in the receiver display and there is no sound.
Thoughts??? Thanks in advance.
