So when I couldn’t jump into multiplayer, I tried out the Halo 2 Anniversary campaign with a buddy and I loved how everything looked and the instant switch to classic view. Really, I am surprised at how it can instantly switch like that.
Anyway, while fiddling with that feature I noticed that during some cut scenes, map transitions, and audio queues, if you switched back to the classic view the sound would stop. If you go back to anniversary view, the sound would be fine. Just thought I would mention this.
