To get the most out of your microphone, please see the information below:

• If you are using an external microphone, for example a USB microphone, check that it is plugged in correctly. You can try disconnecting and reconnecting the microphone as this can force your computer or device to recognise it.
• Ensure your microphone volume is set adequately, especially if you have volume control on your external headset.
• Ensure, there is no other software such as Teams or a video conferencing client open on your device that may be using your microphone. It is best to quit all other applications that access your microphone and camera when you are using Video Call.
• If you have a USB echo-cancelling combined microphone/speaker unit, make sure it is selected for use as both the microphone and speaker.
