Im running 98SE/2000/XPpro. In 98 the SB Live works perfectly but in 2000 and XP the sound comes out full blast. I have to turn the volume sliders almost to zero. I got the latest 2000 drivers and the volume went down a little but hiss was so bad I went back to the old ones. I got the new XP drivers and completely lost the sound. Had to format the XP partition and reinstall to get sound. This has happend on 2 different motherboards. MS knowledge base says its a known issue and to install the latest drivers. This is my only hurdle to getting rid of 98. Think a different brand of card would work. I like the Hercules Game Theatre.
