Sound Output

post #1 of 3
Thread Starter 
So, here is my dilemma:

I am buying a new receiver and 5.1 speaker system to go with it. I will mainly be playing 5.1 DTS .mkv bluray from my PC and some bluray from the PS3. The PS3 will be connected via HDMI to my receiver and thats no problem.
I also have a 2.1 Speaker setup on the desk that I wanna be able to use as well. The 5.1 system has priority

I do not know how best to connect my PC to the receiver so that I make sure I get the best possible quality! (True 5.1 DTS decoding etc.)

Should I connect it via HDMI from my XFX HD5870 GPU?

(How good is the sound quality?)

Should I buy a sound card and connect that to my receiver and the video directly from the GPU via DVI?

I'm kinda lost, please help.

Your GPU HDMI audio will give you the highest quality (up to 7.1 uncompressed HD formats if your reciever supports them). The other alternative is SPDIF (optical 5.1 DTS/DolbyDigital) which your mobo should do so prolly not much point in a soundcard. You can switch the windows default sound device between whatever digital and analogue devices are present (your 2.1 and GPU/SPDIF)
