No Sound from HDMI Port after installing ATI Radeon 5750 graphics card

Also, please look in device manager and see if you have a yellow warning.

Nope...

OK, will reply again once I've tried these things. In the event my card is defective, I bought from Best Buy... do you think they'll replace it?

Well, I cleaned the contacts, made sure the extra power chord was connected, and re-ran the installation, and still nothing. I suppose the next step is to call Best Buy and ask about warranty information?

Well, then, here's something curious. When I downloaded Catalyst Suite again, and went through to Custom install, there was never an option to download an HDMI driver for some reason. Look here, these are all the options I got:

There's an ATI HDMI device available from Realtek.

Realtek

After you accept the download agreement you will see the driver at the bottom of the Realtek driver listing. ATI HDMI Device (in red).

Hey, glad it worked... you never know.

The Realtek audio drivers must not include the HDMI port device for the ATI HDMI drivers to hook into, but that's just a guess.
