my computer is both an htpc and a workstation so it is connected with HDMI to an onkyo avr and to a monitor with vga. My OS is win 7 64. The problem is that I cannot seem to find any way to enable HDMI solely for audio while working on the monitor. Windows seems to require video to be fed at the same time. If I disable the video to the onkyo that I have HDMI to, the audio properties become greyed out "not plugged in" and I cannot use the audio.
Is there anyway to enable HDMI audio within windows without being forced to pretend it is a monitor?
