If you are not able to select the microphone in the ARC Genesis software, you likely need to check the privacy settings on your device to ensure the Desktop applications have access to the Microphone.

If this is enabled, there may be a USB driver related issue which can typically be resolved by uninstalling the microphone driver, disconnecting the microphone, and reconnecting the microphone to allow the driver installer to initiate automatically. 

If this does not resolve the issue you may want to try a different USB cable, otherwise it would be best to contact your dealer for further advisory.
