Oh Look a real question! I have a Home Theater PC sporting a Bluray drive and Bluray software player (Corel DVD HD is the BOMB!) in Vista 32 Ultimate. My video card uses a DVI-HDMI adapter to connect via HDMI to my Onkyo 605. Since my video card doesn't handle audio via that HDMI, I use an audio TOSLINK optical from my PC to my Onkyo ...kiss discrete 7.1 goodbye.
Solution! The (as yet un-buy-able) Auzen X-Fi Home theater HD PCI-e soundcard ...google it or just go to auzentech
Once installed the idea is you connect your PC's DVI-HDMI out to the sound card's HDMI in. Onboard the soundcard, the video and audio are combined to one HDMI out with 24p bitstreamed true 7.1 discrete audio+1080p video HDMI cable/signal to the Onkyo for proper Bluray+Dolby HD master and DTS MA out to 7.1 speakers and TV ...a boy can dream
Is the 605 going to be able to handle a 7.1 PCM HDMI signal from a PC/sound card setup like this? This will be in the ballpark of $300 for this soundcard when it's available and that is another thread on this forum, but my question is... Does the Onkyo TX SR605 have the abilities necessary to handle (theoretically!) this input? Would it be any different than say another HDMI discrete 7.1 audio source? Is there another (than PCM?) HDMI 7.1 audio signal format? I know about analog, but that's a whole 'nuther wiring thing so let's not get sidelined shall we? HDMI ...1.3 ...is the "standard" going to save my bacon?
