From time to time when I start up my xbox while halo 4 is in the disc tray and I load it up, I will have sound while on the logo screens but then once I hit the main menu, there is no game sound. The same thing will happen when I put in halo 4 after pulling out another game. Going through the menu's or entering games does not fix this, it just stays quiet. The way to fix it I have discovered is just to exit to the dashboard and then return to the game. I am not sure if this only happens to me, but I have an xbox 360 Elite, not sure if specific type of xbox is affected, or if its just my copy of the game. Is this a fixable error?
