I have a Windows 7 PC with onboard HDMI connected to my Receiver (Pioneer VSX-821K), via HDMI. The Receiver is connected to a fairly new Vizio LCD TV via the HDMI Out on the receiver.
This Setup works great when all of the components are on.
The trouble comes in when I turn off the TV, which I want to do so I can play music from my PC, but not have to waste energy running the TV.
When I turn off the TV, sound stops, sometimes just for a few seconds, but most of the time, it doesn't come back at all.
I'm thinking this is a Windows 7 issue, where Windows sees that the monitor is no longer on and stops sending the HDMI audio signal.
All drivers and Service Packs are up-to-date, and I don't see any relevant settings in the Sound Devices dialogs in Windows.
This is driving me crazy, please help!
UPDATE I ended up resolving this problem by connecting the S/PDIF on my computer to the Receiver and connecting the HDMI out on my computer to my TV. This solution works, but it is not ideal. If anyone reading this knows of how to make a pure HDMI solution work, please comment!
