What happened is that the sound goes out in the middle of a match on Xbox Live, and the sound is out for the rest of the game, and then at the end of a match, the sound come back, but then it goes out when a new match begins. I tried changing the input on
the TV, I have the Xbox 360 on the HDMI input.
Go into your options when it's happens. Hit start and go to the audio. Change it from Hi-fi or whatever you have it on to just one over and it should pop back in. Change it back to the one you want and continue with your game. It's happened to me a couple
Reboot xbox is the fix. This happened usually in a laggy server where ya were ment to get booted but somehow managed to stay in the server. But yeah no sounds until after the match during the stats page then there's music then next match no sound. Best
to reset off/on xbox.
