I started this thread because somebody was having problems. He persisted, and finally came up with a solution for his problem (it may not work on yours). Here's what he says:

Every case is different, different OS, different
sound cards, etc., etc. I doubt if there is any formula, but the three things suggested (most current sound card driver, current DirectX, and making sure full duplex is enabled) are things everyone could try. The thing that turned the trick for me was going to the website and downloading the most current sound card driver. The other two solutions did not solve anything.
