Microphone and web camera defaults can be assigned within individual browsers.
(A) How to Change a Site’s Permissions in Chrome
There are basically two ways to manage the permissions for microphone and webcam to a site: from the Omnibox or inside Chrome’s settings.
(i) Change a Site’s Permissions From the Omnibox (Address Bar)
This method works when you’ve already set the permissions for the microphone or camera and want to change them while visiting that particular site.
Go to the website for which you want to change the permissions and click the lock icon on the leftmost side of the Omnibox.
From the menu that appears, click either the microphone or camera, then from the drop-down menu, select “Allow” or “Block,” then click the X to save your changes.
After saving your decision, you will have to reload the page for the changes to take effect.
(ii) How to View Permissions From Chrome Settings
The best way is to copy and paste these links in your web address (URL) area:
Site settings: chrome://settings/content
Within Chrome's settings you can manage the default mic and camera, while also allowing or blocking specific websites access to your microphone or camera.
(B) How to Change a Site’s Permissions in Firefox
For Firefox, copy and paste this link about:preferences#privacy, then scroll down to the Permissions section, and click Settings. There you can choose which websites to Allow access to your microphone and camera.
To choose or switch your microphone or camera in Firefox, you'll need to go into your virtual event page or meeting room. From there, click on the Mic or Camera icon that's just to the left of your URL address, and choose your microphone and camera from the dropdown menu.
(C) How to Change a Site’s Permissions in Safari
For Safari, click Safari in the top left-hand corner. Then click Settings for This Website... Under camera and microphone choose Allow.
Operating system settings
On older MacOS, there are not system level controls for webcams, and instead MacOS will default to the settings on the application (Zoom) or browser level. However, if your mic selection isn't saving, there is a system level control of your mic. You can access this by clicking on the Apple in the top left corner of the screen and selecting System Preferences. From here, click on Sound and then select the Input tab. This area will list all input devices that are available, and you can set the default as necessary. Unlike the microphone settings, there isn't a specific area to choose or change your default camera.
If you are using Mojave (10.14) and above, Mac has added system-level privacy settings and permissions. So If you’re having an issue getting your camera or microphone working after upgrading to Mojave, it could be related to some of the new security and privacy features. One of the updated privacy features requires applications to request permission to access your camera or microphone.
To check these settings:
- Click on the Apple Menu
- Go to System Preferences
- Go to the Security & Privacy section
- In the left column you’ll find a section for Camera and Microphone. Click on the device you need to allow permissions to
- In the right column, find the app that isn’t working and check the box next to it to allow it
- You may need to restart the app to allow the changes
(B) Windows 10
In Windows 10, you can set a default Mic, but there are also system-level permissions to allow applications to access your microphone and camera. For both, open up your system settings by clicking on the Start menu and selecting the Settings gear.
From the Windows Settings page, choose System. Within System You can click on Sound or Search for Microphone or Camera. Within these settings you can adjust both the default devices and privacy settings. Type in the search area or click Sound, Microphone, or Camera.
