I saved some money to upgrade my PC and buy a 7.1 sound system. I looking at Harman Kardon's 330 a/v receiver, and Bosse's speakers. And for the Pc's sound card I chose sound blaster audigy plantinum 2 ZS. I also want to use the sound system for PC gaming. In that case, I wonder if the a/v would be able to decode the signal coming from the pc correctly, just as if I had a 7.1 pc speakers system. Thanks for your help.
