No audio HDMI. GEFORCE GTX 660Ti from MSI. It just came out so, not sure if it's supported yet. Any ideas? hdmi audio is my only option for sound. I tried reading through those pdf files but could never get aplay to recognize the device or card or whatever.

Edit: Also note that there were no hardware drivers available so I installed them manually from Nvidia's site, which worked great for video over hdmi, but no audio yet.
