In the Settings of TwitchTV when I turn off the microphone volume or I use push to on talk, I still hear my sound on twitchTV !
– You can turn on or off the push to talk button --> no effect !
– You can turn 0% or 100% the volume --> no effect !
Screenshots verify the mic volume is at 0% and the mic-mute icon is next to the twitch recording icon while outside the menus.
In the new version the same problems too !
