No HDMI audio from new Gigabyte (NVIDIA) GT220 graphics card

[JaimeZX]

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.

Jaime,

Aside from setting Nvidia HD audio to default, you will need to have the latest Nvidia audio driver installed. You can uninstall your current Nvidia drivers (all of them), and when you install this driver, select custom, and make sure audio driver is selected to install.

Here it is: NVIDIA DRIVERS 285.62 WHQL

I'm not sure if you have an Nvidia driver installed minus the audio driver, but if you do: This may or may not work instead of removing all the Nvidia drivers: select install driver - Custom. This may allow you to only install the audio driver (so you don't need to remove all other drivers).

Yeeah. I tried that. Will try again though. Thanks for the suggestion!

It is plugged into your sony receiver instead of the HP projector?

Ah, I don't think you can seperate the sound and video, so I don't think you can have it set up how you have it

I'm pretty sure if the VGA is being used, the HDMI is disabled

With your setup, you will need to use this audio (2):


HDMI video/audio will need to be cupled together (although, you don't always have to use the audio...)

The projector only has Component / VGA / S-Video in. So I have it set up like this:

WDTV - Component video to projector, TOSLINK (optical) audio to Sony
Computer - VGA to projector, HDMI to Sony

I'd be glad to run HDMI from WDTV to the Sony, but the manual says if it takes HDMI in it doesn't down-convert the video to component/anything else, and there's no HDMI input on the projector...

Yeah. That's how I'm getting computer sound now. And I do have a nice Creative 5.1 system... but it's not as good as the full-sized Polk speakers on the receiver.

This is the same for the graphics card.

You can buy a new projector that has HDMI
