i'm still trying to solve the problem of replacing my htpc with one that doesn't have a sound card (just hdmi and usb). is there any avr that with 3-4 hdmi ouputs will allow me to switch any input to one hmdi out (the receiving device will NOT have sound) and at the same time select any of the inputs for a second output (either hdmi or digital audio) which i will send to my 5.1 speaker system. the sound i listen to will often not be from the same source as the video i am watching. i've looked as hdmi matrix products but they appear to not allow two different hdmi outputs. i have figured out one way to do it but it's a bit of a kluge. i want to be sure that i get multichannel sound from all the inputs and don't run afoul of hdcp. thanks.
