4. Note: I can get sound from the receiver using Zone 2 - so sound is getting to the receiver from the HTPC.
This used to work, so I am not sure what changed. I am using an Nvidia video card in my HTPC hooked to a Pioneer SC-1522-K via HDMI. I wonder if the HDMI is not getting initialized properly? Windows and drivers are fully updated to the latest versions.
Any help or clues would be appreciated. Thanks so much!
So what I suspect is happening is this. When you switch HDMI sources, the PC detects a change in HDMI and the capabilities of the system change. The output source no longer is an audio capable device. If you have another audio device then the default audio changes to that.
I'd try this. Go into your audio devices (start, run, mmsys.cpl). What audio devices are listed? Make sure you force the HDMI device to be default device then actually disable the others. This at least prevents switch over. Test and see if that solves it.
If not, after switching away from the PC then back and having no sound, go into mmsys.cpl and reconfigure your audio device and see if you can get sound via the test in that.
