Is there a reason you want audio from the video card so much? Is this a situation where the only speakers are on the TV? Is there no stereo-in or optical available?
It's a situation where I'd really like to be able to switch between my 3 desktops by changing inputs on my monitor only. My monitor has no audio in only line out going to my speakers. The only way to use my monitor as I'd like is to have all the audio sources come in to the monitor via displayport or HDMI. My use case is VHS capture I have one XP PC dedicated to capture and one XP PC dedicated to editing. I know it's weird but you have to do it that way.
One is a PC with nothing except what's needed for capture as almost any other driver will break ati aiw capture cards theatre 200 driver. It has conflicts with everything. That PC works beautiful with a vga to HDMI cable that actually integrates a 3.5mm jack into the hdmi.
I put together the PC that has no audio as the fastest XP PC I could make. 980ti, 4960x, Asus rampage iv black edition motherboard, 2tb SSD as for the editing portion the software requires XP but the faster the better for encoding. The PC works great just no audio.
My other rig is completely modern 4090 system for gaming.
These are my use cases. My issue seems to be beyond simply not looking for audio though. I hooked it up DP to DP just to see if the audio would work and it still doesn't. It's recognized as a DP connection and in the Nvidia control panel tree I get the set up digital audio tab. However, I can't connect to Nvidia high definition audio even tho it's listed in device manager. It simply is not a selectable audio device in the sounds tab. Realtek hd audio is my only option and it has no audio same as before.
Can anyone confirm they have ever got a 980ti to output audio to XP through HDMI or Displayport at all? If so what was the driver? I don't really care about maximizing the ultra widescreen or scaling at this point.
