Halo 2 PC question: would anyone know...

…by any chance how to remove all of the music in the game’s sound mix including any sort of scripted cue? Is it possible without being excessively difficult? Also, can it be done without screwing up the rest of the sound?

Reason is because I’d like to make demonstrating how I believe pieces from the other three “movements of the odyssey”/Incubus suites could have been implemented really well into the middle and end of the Arbiter’s campaign. Unfortunately, as there has never been a volume slider with Halo I cannot do this without the existing music already being underneath. I would also be moving, adjusting and then reintegrating the music that’s there obviously and that’s all very easy, but I need the in-game soundtrack out somehow.

Would be really appreciated if anyone knows. Thanks.
