How do you turn on your microphone on snapchat?

To turn on your microphone on Snapchat, first, open the app and start a chat or a Snap. If you're using the camera, tap the record button to start capturing a video; this will automatically activate the microphone. If prompted, grant Snapchat permission to access your microphone in your device's settings. You can also check the app's permissions in your device settings to ensure the microphone is enabled.
