# Microphone

The Microphone state action lets authors finely control the user's microphone. The author can forcibly mute the microphone or return control to the user.

1. Within the edit Simulation section of the HyperSkill Desktop application, navigate to the Scenario or rules tab.
2. Click on the desired state or rule and locate the state action list to the right.
3. Select the Microphone state action and press the + button to add it to the action list.
4. Choose to mute or unmute the microphone. The microphone stays muted until you unmute it, even if the user tries to unmute it.
5. To unmute the microphone later, add another Microphone state action and set it to unmute.
6. When you are done, press the Save button.

**Note:** You must unmute the microphone the same number of times as you have muted it. For example, if you forcibly mute the microphone three times, you must unmute it three times. Otherwise the microphone remains muted.
