There are a lot of accessibility, and functionality issues that would be solved with a feature like this.
Examples of accessibility would include multiple audio languages, audio description, etc.
Feature improvements for broadcasters could be Mic only audio stream (for broadcasters who play games with their viewers, enabling viewers to have no noise from streamer game audio when playing the game themselves)
The above assume Twitch only allows for one stream of audio/video to be listened to at once. If Twitch opened up client-side mixing, the features in the top-level post would be possible, as well as the separation of broadcaster voice, team comms, music, game audio with client-controlled audio levels to their preference (some might want full volume game audio, others might want background levels if they are working, etc).
