Most microphone issues are caused by problems with the connection between the camera and computer. If there is a loose USB connection anywhere in the chain, the audio will be the first thing affected.
Please ensure that you aren’t using a USB hub or extension with the camera. For best results the camera should be connected directly to a USB 2.0 port on the computer.
In some cases, using a shorter USB cable will help improve the connection. If you are using HUE with a different USB cable, please try the one which came inside your box.
