Anyone experiencing any audio issues?

I was playing Abyssal Chaos with Zayne earlier and suddenly my game sounded pixelated. I thought it was part of the story but going back to the café and other parts of the game sound pixelated and like my phone's speaker has blown.

It's not impacting any other apps, audio elsewhere is fine.

Reinstalling and repairing hasn't fixed anything - has this happened to anyone else before?
