Whenever I start BZ2 my Winamp volume goes way down, but when I exit BZ2 the volume goes back up.

It should be at max, but running BZ2 moves it automatically way down. I have to alt-tab to fix this, in order to enjoy the music.
And then there's this multiplayer voice hell. Whenever I play music I see this (T) blinking like bats out of hell, indicating I'm probably sending voice, while I'm not. While I enjoy my music I don't think others do. How the heck do you shut this feature OFF? I see lots of sliders, but nothing to disable MP voice on my end.
Every time I bring up this issue I'm just shrugged away.
