I don't remember this happening before with me on Twitch, but it's annoying: I keep having ads cut in, which crank the volume up to max instead of the level I had, and then I mute the ads, and then when the game comes back it's muted. At that point, neither muting nor unmuting nor changing the quality does anything. I then have to reload the stream which of course...plays another ad.
It would be nice if the ad just stayed muted if the stream was muted, instead of maxing the volume. It would be even nicer if I could get stream audio back after the fact. Unless I'm just missing something. Maybe sometimes the stream is quiet and I only THINK the sound went out permanently.
