Just about to do another little project and cant find an obvious answer :s I want to take an HDMI signal from my GPU (setup to carry the audio and pic) into a Sony receiver (probably 5200es). I will feed the HDMI out to a monitor and I want to then output the audio via optical from the Sony to a set of PC speakers that have optical in. I wont be using the Sony for audio. Basically I'm looking to use one PC for 2 different setups in my 'project room' . I cant use the Sony for audio as that feeds some of my bass shakers for my race rig. I cant really think of an easy way to test it before I buy a PC speaker setup with optical.
