Okay so I've owned my Halo game for the grand total of four days or so. The first day all I did was play the campaign and there was no sound playing what so ever. In response to this i restarted my system and turned the subtitles back to "automatic" or whatever it was on originally after that it worked fine and so i thought nothing of it. The next day i downloaded Spartan Ops and what not from the second disk only to discover that the sound once again stopped working. I thought it was just a problem with the download so i deleted the Spartan ops and downloaded it again and once again the sound worked fine and I played it again with again no problems. Starting yesterday and today however I tried playing again to find that the sound doesn't work AGAIN even on the main screen or the campaign. But when I start up the system and the "Microsoft Studios" and "343 Industries" screens show up the sound works fine. It's only when i get into the game itself that the sound decides it doesn't want to work. Has anyone else had this problem? Or is it just me?
