I’ve been playing the MCC since the day it was released and I’ve never seen these glitches before until recently. I noticed when I play Halo:CE when I switch to the games original graphics the mouths on the characters don’t move anymore. This happens during both gameplay and cut scenes. Another issue is with Halo 4. Every time I pause and un-pause the game, all sound disappears, except for in the menu. The only way to get the sound back is to save and quit. I wasn’t sure were to post this where someone from 343 will actually see this. I just want them to be aware of the problems because I know their priority is the multiplayer, but it seems like with each patch released to improve multiplayer, the single player starts breaking. The problem with halo 4 is kind of game-breaking unless you don’t mind playing the game with no sound, or never need to pause the game. Has anyone else had these problems?
Has anyone else experienced the issue, particularly the loss of sound in halo 4? I want to know if it’s a problem on my end, or a problem with the game itself. I would really appreciate any response.
ive got the same problem. if i pause the sound is gone. Also have a problem where 2x in the campaign of just halo 4 it glitches out and i cant continue.
I have had that same issue. I doubt it will be patched 
Same issue here, they will get to, fixing it, when they are bless to 
I hope this gets patched since it was likely a patch that caused this problem.
