I've got a couple of PC's in a rack in the basement hooked up to an Octava HDMI Matrix Switch that sends HDMI to my family room surround sound system (with a Denon AVP with the 3D hardware upgrade and a 3D capable Mits RPTV) and HDMI to my bedroom system which just has a Panasonic 1080p plasma (not 3D, but this isn't really an issue). If the matrix is configured to send the same source device to both systems, the EDID it presents to the source is for the most capable system. I've installed an HDMI override that Tulli made that makes the PC's always think they're connected to the most capable system.
Without the override, I have to be careful to have the matrix configured to send each PC to the family room system at boot up in order to get full audio capabilities. Once the boots, the audio capabilities don't change if the HDMI matrix configuration changes.
PC#1 doesn't appear to have any issues. I'm running TheaterTek, J River Media Center, and BeyondTV on this system and so far, audio and video both work well in both rooms for everything I've tried.
PC#2 is used pretty much exclusively for Windows Media Center with a pair of Ceton InfiniTV 4 cards for tuners. It works fine on the family room system. On the bedroom system video works fine and I get audio when navigating Windows Media Center (the blips that you normally get when scrolling through the recorded TV list, for example), but when I try to watch a recording, there's no sound. I'm assuming this is because the PC / Windows Media Center is sending an audio format the TV doesn't support.
One obvious option to resolve the problem with PC#2 is to add a low-end receiver that can handle all the current audio codecs (such as a Denon AVR-1612) and a pair of small speakers (or a sound bar that supports the various audio formats over HDMI) to the bedroom system, but I'd prefer to keep this system as simple as possible. This is a simple solution, but would probably cost at least $400 for a budget receiver and a pair of half way decent speakers (I could pick up a pair of used NHT Super Zero's pretty inexpensively, so the bulk of the cost would be in a receiver).
Another possible solution could be to install a device that could install inline on the HDMI cable, convert all audio formats to 2 channel LPCM, and pass along the original video and down mixed audio to the TV via an HDMI output. This would be nice because it would keep the bedroom system simple. But I'm not aware of any such device.
Is there a simple way (emphasis on simple) to tell Windows Media Center to output audio the TV in the bedroom will support when I want to watch TV in the bedroom and then change back for use in the family room? To keep usability high, I'd rather not have to exit WMC, change my audio config, and restart WMC each time.
