Zoom: Troubleshoot Audio (Faculty & Students)

This document provides an overview of how to test audio in Zoom. The screenshots in this article may not look exactly like the version of Zoom you are running; if not, try updating Zoom on your computer.

Before a meeting

  1. Always run an audio test before joining or starting a Zoom meeting. 
  2. During the test, if you cannot hear any audio:
    1. Make sure your computer speakers are on/not muted. (Look for your computer's audio controls and turn up the volume.)


    2. If your speakers appear to be on and the volume is up, but you still cannot hear the audio, check Zoom's audio settings and select a new speaker. Click the upward arrow to the right of the Mute button at the bottom of the Zoom window. Choose another speaker from the speaker selection list and try the audio test again. If you do not see a speaker listed, this means your computer does not have any speakers connected. You will need to plug in a headset or external speaker, or use the Switch to Phone Audio option to listen via your phone's speaker. 



  3. During the test, if you cannot hear the audio your microphone recorded:
    1. Make sure you have the right microphone selected (e.g. maybe you are talking into your laptop's mic, but Zoom is picking up an external mic nearby). To select a different microphone, click the upward arrow to the right of the Mute button at the bottom of the Zoom window. Choose another microphone from the microphone selection list and try the audio test again. If you do not see a microphone listed, this means your computer does not have an internal microphone and you do not have another mic plugged in. You will need to plug in an external microphone/headset or use the Switch to Phone Audio option. 
  4. During the test, if your audio sounds muffled or distorted:
    1. Try using a different microphone (e.g. a headset). 
    2. If you do not have another mic, click the upward arrow to the right of the Mute button at the bottom of the Zoom window and choose Switch to Phone Audio Call from the drop-down list. 



    3. Follow the prompts on the next screen to dial in via telephone. Once you've completed these steps, you will be able to speak and listen through your phone's mic and speakers. 




While you are in a meeting:

  1. You can switch your audio source at anytime, even while a session is ongoing. If attendees cannot hear you well (if your sound is cutting out, for example), you can select another audio source from the audio menu. To switch audio, click the upward arrow next to the Mute button and choose Switch to Phone Audio or choose another microphone from the top of the menu.



  2. Remember, if you use the Computer Audio option, that means Zoom is relying on your internet connection to transmit audio. If your internet connection is not good, your audio will not be good. People on the other end might say you are cutting in and out or that you sound like a robot. To fix this problem, you can either:
    1. Use the Phone Call audio option
    2. Try moving closer to your wireless router (for example, if you are downstairs and the router is upstairs, move upstairs into the same room as the router)
    3. Try plugging your Ethernet cable directly into your computer (rather than into the wireless router)
