On the startup the screen says "CD rom initialized" and "audio tracks found" but in the game I don't hear any music (of course also the alternate MIDI music isn't playing).

I'm using Windows 7 64 bit. Does anyone have an idea what may be the cause for the lack of music?

Edit: Aaargh, it does play - I only knew the MIDI soundtrack so far so I expected a similar audio track. I mistook the audio track for ambient sfx. Sorry.

Edit 2: It's getting better and better. The music was just extremely quiet. After turning the SFX down I actually finally heard the audio tracks. Yeah, CD audio soundtracks, those were the times... :P
