No Audio Over HDMI

My Nvidia sound card comes disabled by default.

Theses are the outputs:

lists nothing, but that could be because I disabled the built-in sound card at the Bios.

This HDMI cable probably only works on monitors with sound built in, but the graphics card works through its D-Sub output.

You mean you're using a VGA to HDMI converter?
That's not gonna work unless the converter takes input from HDMI and splits the audio off (sp/dif or analog)
HDMI/HDMI isn't an option?

This is a very odd / confusing statement. Your first post provided diagnostic information, but didn't specify the problem: what are you trying to do / what do you expect, and how do the results differ from that? I gather I must be misinterpreting the quoted statement as it sounds like you are saying you are not getting sound over HDMI when you plug it in to a monitor that doesn't have speakers: well yeah, a monitor without speakers will not provide sound output (clearly I'm misunderstanding the problem here - I hope).

The cable goes from HDMI, on the graphics card, to red, white and yellow. What I am saying is that if it was from HDMI to HDMI the result would be different, provided the monitor had speakers.
The built in HDMI, from the built in Audio, does not offer a different result. Sound Preferences just says its an Output, does not detect any HDMI on the Hardware tab.

Ok, I just did the test. The NVIDIA GK208 card's HDMI output has sound and video through my television.
On the Hardware tab, in Profile, instead of "Off", now appears "Digital Stereo (HDMI) Output".
