This article explores 3 places to check on your device running Mac OS to ensure audio has been set up right for Coviu.

Last Updated: Feb 2021


Note: The below screen captures are from a device running Mac OS Big Sur. 

Getting your audio to work can be configured by checking through how your device running macOS and your chosen web browser are configured.

Unless you have done so already, it may also help to do a quick Coviu Pre Call Test to learn more about the existing compatibility of your device and connection for call-audio.


1) Web browser: Site settings

Allowing site-permission to access your audio sources when asked from within your chosen web browser is needed for a successful Coviu call. Check if Coviu has been granted permission to access your microphone and speaker by checking with your web browser Site settings to ensure that permission is set to 'Allow' for both; Microphone and Sound.



    • In Chrome, this can be easily seen by clicking the padlock next to the website URL Clicking here lists any site related information. If you are not seeing any of your sources here, head further by clicking 'Site settings' to explore all site-related permissions to confirm and that the required sources are set to 'Allow'.

2) mac OS System Preferences: Sound

Make sure that your device audio is not set to mute or an inaudible volume for a call. Open your macOS System Preferences usually found on your macOS Dock or by typing the same in the Spotlight Search function located at the top menu bar on your desktop. Once there,  click the Sound Section, and then from there, ensure that both microphone & sound sources are picking up sound or audible under the Input and Output tabs 

    • Under the 'Input' tab you can check if your selected microphone is actually picking up audio and has not been set to mute. 
    • Under the 'Output' tab you can check if your selected sound source has been set to an audible volume or mute.
    • If you are not seeing your required external microphone, speaker, or headphones being listed here, ensure that they are still powered and connected to your device. 



3) mac OS System Preferences: Security & Privacy

Finally, have a glance at the existing macOS level access to the microphone that is granted to your web browser. Head to the Security & Privacy section under the same Mac OS 'System Preferences'. Once there, check under the Privacy tab to then make sure  Microphone access is enabled for your chosen web browser to then make available for a call.

    • If you have a password set up on your Mac, click the 'padlock' to the bottom left of the window to unlock and then make changes under the same 'Privacy' tab.

Now you have looked at all the right places to check on your macOS device and your audio should start to work for calls!


You can return to Coviu, then check via the in-call Settings button from the top left corner after entering a room or session to ensure that both your microphone & speaker sources have been assigned correctly by your web browser under the sections Select microphone and Select speaker.


  • If you are seeing multiple sources listed or note that none have been assigned with a tick by your web browser, please make a selection for at least one source to be made available as the microphone and speaker for a call.
