I installed a ASUS GeForce GTX570... it has the capablility of sending sound out its HDMI port. However in "playback devices" it is not listed. The driver is working fine under, device manager. I already made audio devices show disabled and disconnected devices. Still nothing!
I have an Asus Rapage extreme II mother board, I am runninf Win7 64 bit...8 gig ram... intel processor.
