Here's how to enable Audio Monitoring on your iOS Device:
- Open Settings on your device.
- Scroll down to the section that lists all the apps installed on your device.
- Tap "Switcher".
- Under Switcher Settings, toggle on the "Audio Monitoring" option. When it's on, the toggle will be green and the button is on the right side.
When this option is enabled, the audio captured by the device goes through the headphones.
Please note that you can only monitor the audio coming from the device in which you plug the headphones. You cannot listen to the remote camera audio input from the video mixer.
