Mute your microphone in Meta Horizon Worlds
When using Meta Horizon Worlds, other people around you will be able to hear you talking. If you prefer to not have anyone hear you, you can mute your microphone. You will remain muted until you re-enter Horizon Worlds or unmute yourself.
To mute and unmute your microphone, turn over your left wrist and select the Microphone icon.
Note: Your microphone can be enabled or disabled in the Apps section of the Settings menu on your Quest 2.
