Separate Audio Volume for streaming/videos and calls
You should include two different speaker level bars:
1. For calls/videocalls audio volume
2. For twitch streaming channels/videos audio volume
So onceyou have perfectly adjusted the volume for hearing your gaming mates perfectly without high level distortions, you don't need to readjust any volume to avoid hurting your ears (there is a high gain difference between both volumes).
You would only need to set it once at settings menu as the other sound options.
