While listening to anything with audio, the volume changes spontaneously. I have tested this with Chrome and the problem doesn’t happen there. I actually have Brave running on another computer previously and this issue wasn’t a thing. It’s only happening now on a new machine where I installed Brave for the first time.
I’d expect volume to stay consistent given the provided setting and not change on it’s own.
