Feature Description

Relevant feature exists in an FFZ addon already: https://github.com/FrankerFaceZ/Add-Ons/blob/master/src/smokemotes/index.jsx#L387

Essentially, twitch keeps messing with the quality setting and (at least for me) keeps dropping the audio quality noticably because of it. In some instances, the stream entirely stops if a stream is not foremost on any window. Very annoying behaviour.

Mainly opening this to track, seems reasonably easy to implement even for first-time contributions.
