Yeah I have the same issue, I think it's a bug.

If you sounds are set to 0, there's no way in hell you're gonna hear it.
No, not the ingame, the OS sounds. Open mixer and turn Emps's music off. Simple fix.

If you close emps-world downloadable client while playing unexpectedly, sometimes the music lingers, and the Java client stays up in the background, but the actual game is not visible. You just have to hit Ctrl Alt delete, then end the correct Java task in there. Happened to me too.

See, there is a way in the hell, this could happen.
