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

If you haven't 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.

Allow your web browser to access the Camera, Microphone and Sound

For Coviu to work on your web browser, you will need to allow the browser to access your audio sources when asked. 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 Microphone, Camera and Sound.

Allow web browser access
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.

Checking your 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 icon, and then from there, ensure that both microphone & sound sources are picking up sound or audio under the Input and Output tabs.

Mac OS system preferences

    • 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.

Checking your 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 your mac 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.

Mac OS microphone permissions

    • 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.
