For some reason whenever I enter a mission the loading music would pause and then suddenly continue. The Dialogue and sounds would be removed and then suddenly a heap of dialogue would overflow on the other dialogue pieces. Another thing is that some of the missions would kick me back to the Main Menu. This is only happening in the Halo Reach Campaign and nothing else, can somebody help me fix this?
I’m not certain about the dialogue problem but regarding your other problem, performing a hard reset of your console normally sorts it out.
