Audio cutting out

I'm getting a bug where my audio will repeatedly cut out (voice lines, sound effects, background music/ambiance). It hadn't started happening until yesterday. I don't think it's my computer as it doesn't happen on anything besides League.

It doesn't happen in the client, only in game. I also ran the troubleshooter and nothing came of it.

It's happening with every champion I play, not just with new champions or skins.

I wanted to attach a clip, but my usual screen recording software, which has worked fine with league in the past, was working like powerpoint. I'm just going to guess this is a result of Clash, but any advice/guesses are welcome.
