Hey, so I started playing D2 on my computer via steam. I am using a wireless headphone (Sennheiser momentum 4). When I boot up the game, audio is great, but once it gets to the character screen, the game seems to take over and the sound goes from a normal sound to a horrible empty sound...like its coming from the end of a tunnel. What is going on?? Is this is a known issue with D2 and Steam?? Please help!
