HDMI Audio output - how to get it to work???

I only have this problem with 7, so I know it is not a hardware related issue. I simply can not get any sound out of my graphics card (seemingly) through HDMI.

I have my bios setup to play audio from it. I've followed what everyone else has done when using the search, I have zero success. It worked before using 7, so I am 100% confident that this is a 7 issue (because it still works on Ubuntu!).

All drivers and software is up to date too.

Mobo: M3a79T Deluxe
CPU: Phenom II X6 1090T
GFX: GTX 275

I am ready to pull my hair out.

I want to reinforce... it works on my Ubuntu install!

When you plug the HDMI cable into the HDMI port on a video card, it should automatically change the default audio playback device to the HDMI and you get audio. If it's not doing this automatically, you will have to manually change the default audio playback device in the Control Panel/Sound Panel playback section.

The GTX 275 doesn't have built in audio for HDMI and requires a SPDIF cable from it to the SPDIF header on the motherboard or sound card. I assume you have it connected as such seeing as it works in Ubuntu, so if you haven't you need to set it to SPDIF out of the sound card in the Windows playback options to get sound from HDMI.

It must have built in audio, because it has worked in the past, and it is indeed without the SPDIF, as it works without it.
