EDIT: As usual, I resolved it not long after actually asking for help. Turns out the SPDIF cable going into the motherboard was backwards, and switching them let the sound work gloriously, through both DVI ports (with two DVI -> HDMI adapters). Apparently this is not an uncommon problem, but luckily fairly harmless.

Thanks to the mod who moved my post.


Jasor31385, I'm having the same problem with no drop-down menu on the "Change Resolution" page. I have an HDMI Audio Output sound device listed in my Windows playback devices, but I can't get sound to go through. I've tried many things: Realtek and default Windows audio drivers, every combination of bios settings, forcing an install of NVIDIA HD audio drivers which failed to install automatically... no luck yet. I'm trying to reenable this after turning it off two years ago when I first put my computer together, so I know the hardware is capable of it. I'm trying to connect to both/either a monitor and HDTV which support audio through HDMI. Neither is Philips brand.

-ASUS P6X58D-E motherboard, with SPDIF to the graphics card. BIOS currently set to HD Audio Enabled, with SPDIF set to HDMI; not SPDIF, which leaves me with 2 digital optical playback devices instead of 1 + HDMI. I've tried both settings, though .I know that sound in general works, since analog out from the onboard sound to external speakers works fine.
-MSI N250GTS Twin Frozr 1G OC (NVIDIA GeForce GTS 250) 2 DVI outs with DVI -> HDMI adapters. I've tried from both ports, but right now I'm just using the primary port without anything else plugged in to try to isolate the problem.

There's only ever 1 audio-related device driver listed at once, contrary to what a lot of other people with similar problems seem to have. Whenever I install the latest package of NVIDIA drivers, while there's an HDAudio folder in the expanded files, it's never listed when I run setup. And running the individual HD audio driver ends up with the message "The NVIDIA Setup program could not locate any drivers that are compatible with your current hardware." I'm really out of ideas at this point, going to try Nvidia support sometime this week. Open to ideas, thanks. (64-bit Windows 7 Professional, by the way.)
