A. 1. Check app permissions: Ensure that YoHo has permission to access your microphone by going to 'Settings' > 'Apps' > 'YoHo' > 'Permissions'. 2. Restart the app: Close and reopen YoHo to reset the microphone settings.

B. 3. Test the microphone: Use another app (like a voice recorder) to check if the microphone is functioning properly outside of YoHo.
