Turning the microphone allows you to communicate by voice while in an event or a world. In events, this may be possible only for the staff and users granted guest status.
To avoid sounds from the speaker affecting your experience, please make sure to use earphones when you use the microphone. (If you use the speaker, this could lead to howling, affecting other users’ experience as well)
By turning on the microphone icon indicated below, the mic will turn on. The image on the left indicates how the icon looks when it is off, and the right shows when it is on. (Image is for desktop)
Click on the below icon, which can be found on the left side of your menu, to use your microphone.
