First post, hello all. My setup: Samsung PN58C590, Creative Fatality X-Fi Sound Blaster, Windows 7 PC, PS3, HD DVR, Pioneer VSX-1021-K, wifi, and iPhone 4. I've connected the sound card and the TV to the receiver via digital audio cables (TOSLINK) and everything else is HDMI. I cannot get sound except through the PC. Do I need to connect the receiver via HDMI also?
