I got a Creative Sound Blaster Audigy FX yesterday and whenever a I play games there is a high pitched buzzing/whining sound coming from my heaphones. This never happened with the onboard audio and when I alt-tab it stops. I have a suspicion that it may be from interference from my GPU due to the only PCI-e slots on my motherboard being right next to it. If it is then how can I fix that? Thanks in advance!
