Testing Audio Equipment


Prior to actually utilizing UNC Asheville Zoom Meeting individual licensed accounts, users are highly encouraged to ensure that their computer or mobile device audio equipment (speaker and microphone) is operational and will support Zoom Meeting system requirements.  The use of the below articles will provide contextual assistance for ensuring associated equipment is functional within UNC Asheville provided ITS equipment, as well as any personally owned equipment used within web conference meetings. 

UNC Asheville ITS computing resources

All UNC Asheville computing resources are supported by the ITS Customer Support Technologies (CTS) unit.  While every computer/device is issued with properly functioning audio speakers and microphones (factory installed), occasional issues may arise that disable associated software drivers, audio device software, or result in 3rd party software blocking access to the equipment.   Many Zoom related audio technical issues are a result of clients not confirming that the correct audio equipment is available for Zoom use and testing both speakers and microphones prior to starting a Zoom Meeting as Host, or connecting to a scheduled Zoom Meeting as a participant.

Issues with ITS supported resources should be communicated with ITS Service Desk staff via the email portal.
