Halo: Reach (Xbox One) - NO AUDIO

Hi guys, I downloaded Halo: Reach tonight from the Games store on Xbox Live, since I never actually played it originally when it was released on Xbox 360. After customising my Spartan, I decided to start a Heroic Solo Campaign session, however, during the initial cinematics, there is NO AUDIO whatsoever. This is also the case once gameplay commences, e.g. when firing weapons etc.
Is anybody on here familiar with this issue? If so, do you know of a solution to this problem? I would very much appreciate quick responses as I was actually pretty excited to play through the Halo: Reach campaign while I still have some spare time.

Thanks in advance,

I fixed this issue on my One X by restarting the console. Not sure if this fixes it permanently though.
