I have an XFX R6570 Core Edition graphics card that I was using successfully for a year or so. Had to upgrade from vista to Windows 7 (64 bit, ultimate, SP 1). For two days, I have been trying to get the audio to work. Video works, but the audio device manager shows "AMD HDMI Output, AMD High Definition Audio Device not plugged in."
When I go to an application (XBMC) it doesn't give me the choice to select that as the audio device.
Have reinstalled catalyst and drivers multiple times. Properties on the device show its working (just "not plugged in"), and the driver is 18.104.22.16819
It is obviously not that the card isn't seated, because it was just working a day or two ago in vista, and when I reinstall catalyst, it detects the card and installs the audio device driver (in the custom install menu)
I have the same hardware configuration I had before I upgraded windows. HDMI out to a Yamaha receiver, to a sharp tv. In the computer (emachine with AMD Athalon 64 dual core processor) i have this card, and an M-Audio Audiophile 192 card.
Thoughts? I have researched this extensively and can't find answers.
