TX-SR605 Home theater system? ? I'm looking to hook my PC up to the receiver, but I need to make sure I can assign the digital Toslink audio connection to the HDMI video connection because the audio portion wont be transferred from my PC's DVI to HDMI connection to the receiver. I was wondering if any one new it the term assignable meant I can assign a separate audio channel along side the HDMI connection? ----- http://www.avland.co.uk/onkyo/txsr605/rearlrg.jpg -----
