Audio Glitches

I know this has been discussed before, but this is my second night playing Forza 5 and now all of a sudden after purchasing the GT-R… the audio started acting up, popping, muffled sounds etc.
What’s going on with this? Is there any plan to fix it or not?

closing and reopening the game is the only solution to this problem.

It will usually be fixed by shutting down the console and booting it back up.
