First - english is not my native language, so please don't blame me for any failures I have an Audigy running an 5.1 Analog System running. My problem is that when I test the movement->rotate xy in RightMark 3D Sound: Positioning Accuracy Test with the setting System->DirectSound 3D Hardware my two front speakers are very silent in difference to the back or center speakers. When I start the same test with System->DirectSound 3D Software I have no (or maybe minor) problems. Same effect turns out in 3D Sound supporting games like Tribes:Vengeance or Riddick Escape from Butcher Bay if I turn my character before a noise source. So I am deaf to a large range to left and right... To say it more exact - with hardware accelerated sound I only get very silent sounds from 315 and 45 degree in comparison to the other degrees. As a quick fix I turned up the volume for the front speakers at the 5.1 Analog System. But the side effect is that they make a little noise which makes me very unhappy . Setting the multimedia settings from full hardware accelerated to a step fewer did not help.
