Problem with Geforce 9600GT HDMI audio

[Keroc14]

So i've connected my 9600GT via the SPDIF connectors onto my mobo(Asrock 970 Extreme4). I cant however set the sound to a HDMI device in Windows 7. Do i need special drivers for the audio to work? I am really lost here. Any help would be greatly apreciated.

Which exact card is it?
As far as I know, the 9600's didn't process audio.

When connected via SPD/IF, you don't select HDMI as the audio device you select the SPD/IF device.

It is sometimes called something like "Realtek Digital Output".

Nvidia GeForce 9600GT. It does have the option as discussed in this thread

The SPDIF output aint on the list either. Just the Analog, Digital and USB device that ive got connected. I've also turned on show disabled devices but still no HDMI or SPDIF output in the list.

Try selecting the digital output output. As I said, sometimes it is just labeled as a digital output.

I've tried that. Doesnt work. I think that is just the spdif on the back of my comp

Actually that thread you linked to verifies that in that gen of card, Nvidia didn't have an HDMI audio option. ATI did, but not Nvidia. Nvidia didn't come out with a true HDMI audio option until the 400 series.

Don't expect anything but 400 series cards and beyond to pass through both video and audio. The 200 series had a funky mini cable that was supposed to pass onboard audio to the HDMI port on the GPU via connecting it to the MB header and a small port on the GPU, but those never worked.

Even the current gen with HDMI A/V passthrough can be hit and miss depending what peripherals you're using. I just tried a 660 Ti that refused to show the Nvidia HD Audio device as ready for use. It always showed it as unplugged. I've seen others with similar stories.

I don't even feel Nvidia has better driver support lately, and am seriously considering going AMD.

That has been on their cards since G92 was introduced. There were even 8800GT and 8800GTS cards with that port, and it most certainly did work.

Its the same funky mini cable as i've got. Except mines not working apparantly

Agreed. 9600GT series doesn't an onboard audio card, it needed an sperate soundcard to handle the processing which was buggy at the best of times. It was the main reason ATI was such a big hit for HTPC users as it was first to adopt proper HDMI with video and HD audio through a stadardised cable. Nvidia has caught up in this respect but you need a modern video card to exploit it.

Keroc14, I doubt you'll get it working. Might be less hassle to find a cheap $50 video card that can handle your audio requirement without fiddling.

Actually a MB audio header to connect to the GPU, but as mentioned, too buggy to be trusted, as Keroc just verified, as have many others.

Thus I fail to see your point about them "working" newt. If by chance a few out there somewhere got them to work when most didn't, it's not exactly a "working" tech in and of itself.

Like I said, HDMI implementation is something Nvidia has never been very good at. They probably don't even have the necessary engineers on their staff to deal with it properly.

Hmmm well i geuss ill just have to upgrade my videocard if i want to transfer audio to my TV. Thanks alot for the help either way! Really appreciate it!
