i have the asus a8v with 8 channel audio, i have a 5.1 setup up, but whenever i try and play anything the system is lagging the audio so it is playing at times like it is in slow motion, i dont understand i have 1gb of corsair, a 3000+ amd 64 bit, and an 80 gb hard drive, if i close all my programs it will play fine, but even typing right now it is playing in slow mo any thoughts?
