I’ve noticed that the in-game music won’t stop playing over the cutscenes in Halo CE, and the music from the cutscenes and the glitched music that won’t stop playing merge into a mess of just sound. I noticed this after playing Halo CE a few days ago, specifically at the end of The Maw, and also today after updating the game, which suggests that it isn’t just a one-time bug. I also think I remember the problem in a few other missions, although I don’t remember which ones they were.
