So I'm stuck solving this annoying sound problem. Every time I hit ESC in game for Pause, I'm losing diesel engines sound, only way to make it come back is by changing the speed. It's really frustrating and I'm somewhat tired of looking for solutions over the web already. So I learned that audio hardware acceleration has been disabled for windows vista and win7, perhaps this is the case why I keep losing sounds ? Any workaround ?

Edited:
Perhaps I should mention that I'm using onboard Realtek ALC 888. Still searching for solutions..
