I am planning to run my computers audio to my reciever and send it to my 7.2 sorround sound setup and I am not sure how to run the sound form my computer to my receiver and its speakers to obtain the best quality of sound for my gaming and some mp3/digital music, and maybe a bluray once in a while (mostly i would use my ps3 for that)
1) Would I be better off running a toslink cable to send the signal, even though it only handles 5 (5.1)channels of sound, or would I get better sound using the HDMI out put on my video card?
2) I think ATI HD5970 has HDMI 1.3a and outputs a signal capable of carrying a 7.1/7.2 signal out to my receiver, but how good is the sound quality?
3) If I use the HDMI on my 5970 does anyone know what it uses to decode this sound or does it send it encoded? aka does it use any hardware to convert it to analog or does the sound stay digital to my receiver?
4) I am also considering a new soundcard instead of my onboard audio, would this make any difference at all since I will hopefully be using the HDMI out from my ATI HD5970 to send the sound to the receiver or does the video card have its own signal and bypass the use of the sound card all together? aka does the 5970 sending a signal via HDMI use the soundcard or its own audio processing?
