Forza Motorsport

Hi all I have gone back and started playing the original Forza Motorsport (first game) on my Xbox 360 while I wait for the Xbox One I have ordered. I was wondering why the sound keeps cutting out and if there is anything I can do in the setting of the console or game to stop this from occurring. Also been quite impressed with the graphics , they are allot better than I was expecting (I haven’t played Forza in a couple of years).
