Ok, so the switch is really not in the picture yet, then? You bought it hoping to solve the loss-of-audio issue...
I've been reading good things on this forum about the monoprice but i'm not sure if it will do what i need it to do, like what these guys are saying up there about "EDID spoofing" and audio downmixing.
Adding anything HDMI to this mix is not going to help. You've got some incompatibility between your AVR and the HTPC's video adapter. If you're not using the HTPC for Blu-ray content, you could use a separate digital audio link to avoid HDMI audio issues (if the HTPC has an output and your AVR can map a digital input to an HDMI source).
i just tried going component vid out from avr to tv but the avr doesn't allow it. if it's hdmi in it must be hdmi out. i dont know if that would fix my prob but it sux none-the-less
That's the "rules" of HDMI - no analog downconversion... If your HTPC can do component output, that would help, and your AVR likely will upconvert it to HDMI so you don't have to run separate cables.
You should do some more experiments. Switch sources on the AVR without the display attached and make sure there's nothing going on there. Make sure all sources are set to "bitstream" HDMI audio. Turn off any CEC or "HDMI control". Do you only lose audio if certain codes (DTS vs DD vs PCM) are being used? Does it happen switching between anything other than HTPC?
