A long time ago before discord had a big update there was a microphone mute button AND a sound mute button in private calls. After that big update there was only the microphone mute button. It really bothers me to not have that sound mute button if for example i want to listen to a video for a bit without having to tell a friend to be quiet or even leave the call. Especially in a groupcall where more than one person speaks at the same time it’s just really annoying to not be able to just turn that off for a few seconds. So on mobile it would be great if we could have that back next to the microphone mute button!
