Hi. I have a Razer Barracuda AC-1 sound card, and it sounds great, but when I play Oblivion I get these high pitched screeching sounds. If I turn down the ESP all the way, it greatly reduces the screeching, but it still happens once in a while, and it is very annoying. I tried upgrading the drivers, and I removed all of the Creative drivers but it did not improve. I also went into the windows mixer and shut everything down except the volume control and this greatly improved things, but I am still getting the screeching. Anyone have any ideas??
