I have an idea about that Twitch should have support for two or more audio channels, for example you could stream voice and music individually.
Then the viewers can control the volume or mute of both of them individually.
Expandation ideas of this? I would love this feature as a daily viewer of many streamers that have music that I sometimes don’t like or is too loud or too low.
Dual audio is certainly possible, but this forum is only visited by developers working on the api & chat systems. To ensure feedback (either complaints or suggestions) are seen by managers in charge of all parts of twitch, you should email feedback@twitch.tv
