After a couple of matches, I will lose sound to either my console or just the game. I have to disconnect my controler and reconnect to get sound back. It been going on for couple day already
A simular thing was happening to me also during launch week, however it seem to go away… as in its not happened again for awhile now.
That happened to me, but I was able to get it back by pressing the middle button to open the dashboard, then reselecting the Halo tile. No reset required.
