HDMI audio doesn't work, no audio devices detected.

Alright here's my situation:

I have a Core2Duo PC running Vista Home Premium 32 bit, hooked up to my TV using a HDMI cable. This has been working fine for 2 years now. Yesterday I decided to add some more RAM to this PC (4 GB instead of the standard 2 GB to be exact). I know 32 bit will only read 3 GB but I was thinking of upgrading to Windows 7 64 bit later.

Anyway I booted up the computer, worked fine of course, even watched a movie or two without problems. Then this morning I booted up the PC and I suddenly noticed the volume icon saying that there were no audio devices detected! I checked under Hardware and there are no audio devices whatsoever! So my HDMI cable is still giving me picture but no sound! Seeing as I'm using onboard audio I immediately booted into the BIOS and although I couldn't find a specific option that said onboard audio I did see something audio related being "HDA" (I assume HD audio) on automatic, the other option was ACRealtek97 or something. However it was enabled so no luck there.

Does anyone know how all of a sudden my HDMI cable isn't providing audio anymore? I even checked my Nvidia card which also stated that HDMI audio was enabled.

I hope anyone can help me, thanks in advance.
