Player audio being turned off after a few minutes of play

A few months ago I used VRchat (don’t often) and there were some guys tooling around and they convinced me to hop through a portal and when I went back they had scampered and a little while later I lost sound. I quit the app, cleared my cache, relaunched and everything was fine. But I have been having an issue with settings on my computer changing? Been talking with Steam about it for a couple of months and I don’t know if it is related but it was around the time the issue started. There was also a big Windows update and obviously Steam updated as did all my drivers. There were quite a few people talking about issues with Steam after the update and so I assumed that was the problem but I wonder???
