My Cam/Mic isn't working

By clicking on the Cam/Mic button in your room, you can select the microphone or camera that you'd like to use for your meeting. However, in some cases Whereby won't detect a cam or mic, or the device selection won't save. In these cases, there are a few things you can do get everything working again!

In this article

First Steps

For some users, we've found that having another video conferencing program open like Skype or Google Hangouts can cause Whereby to be unable to access the cam/mic. If your cam/mic buttons are greyed out, it's possible that this is what's causing the problem.  In this case, the first thing to check on is if your browser is up to date. We support the most recent versions of our supported browsers, so double check that there isn't an update for the one you're using! There are links below that walk you through updating your browser if you don't know how to: 


If you are using an older operating system like Windows Vista or XP, these no longer have support from Microsoft or browser teams like the Chrome and Firefox; and they won't be able to run an up-to-date browser. In these situations we highly recommend you update your operating system to a more current version. 

If your browser is up-to-date, it's possible that this is caused by a stale mic/cam permissions cookie, or possibly because of another application that's taking priority access over Whereby.

In this case we recommend clearing your cache and cookies for your entire browser and then restarting your computer. Sometimes a reset of your system environment will resolve these types of issues, so this is a "catch-all" solution before further investigation is required. Instructions for clearing your cache and cookies for our supported browsers are linked below:

Check your system and browser settings

If resetting the system environment doesn't solve the problems you can try the below items to resolve the issue!


 Confirm the Microphone/Camera settings for your operating system

MacOS 10.14 (Mojave) and newer

In MacOS Mojave, Apple has introduced some system-level privacy controls for your mic and camera. These are great for privacy, but it is possible that your browser was mistakenly blocked from accessing your devices. You can check on this and allow your browser to access them from the Security & Privacy section in your System Preferences. 

To access these settings, do the following: 

  1. Click on the apple in the top left > select System Preferences
  2. Click on the Security & Privacy section
  3. Click on Camera in the list of options, and tick the box next to your browser to allow access
  4. Repeat Step 3 for your Microphone
  5. After doing this, restart your browser for the updates to take effect

MacOS 10.13 (High Sierra) and older

If you use an older version of MacOS, there are not system level permission for your camera, and instead MacOS will default to the settings on the application level. However if your mic selection isn't sticking, 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.

Windows 10

In Windows 10, you're able to set a default Microphone, but there are also system-level Camera permissions on what applications can access your camera. For either of these settings, the first thing to do is open up your system settings by clicking on the Start menu and selecting the Settings gear.

Default Mic

You can adjust the microphone settings by typing "Mic" into the search bar and going to the Sound settings. Scroll down to Input and use the dropdown to select the proper input device

Camera Permissions

Camera permissions can be accessed by typing "Cam" into the search bar. These settings are under your general Privacy settings, but search is the easiest way to access them. From here, be sure that your browser has permission to access your camera.


Confirm the Mic/Cam settings for your browser

Google Chrome

Mic and Cam defaults can be accessed in a number of ways in Chrome, but the easiest is to paste the following links into your URL bar:

Cam:  chrome://settings/content/camera

Mic:  chrome://settings/content/microphone

From these areas, you can manage the default cam/mic for Chrome, and also whitelist or block websites from accessing your cam/mic! Be sure that Whereby is listed under the Allow section.

Mozilla Firefox

In Firefox, you can also use a URL link to get to your privacy settings. Start by going to about:preferences#privacy, and then looking under the Permissions section. Here you can adjust which websites are allowed to use your camera, and you'll want to see Whereby listed as Allow.

To adjust which camera or microphone Firefox is accessing, you'll need to go into a Whereby room. From here, click on the icon that's just to the left of your URL bar, and you'll have a dropdown menu where you can select the camera you want to use.


In Opera you can get to settings by typing " settings" into your URL bar. From here, click on Websites in the left hand menu list. Then scroll down to the Microphone and Camera area, and use the dropdown menus to select the default devices. You can also adjust your permissions preferences and set up Exceptions as necessary.

Still not working? A couple more things to check....

  • Some browsers are not able to connect through strict networks/firewalls. Also there may be bugs in the browser causing problems with connection. If you are experiencing this, try switching to another browser. Currently Firefox is not supporting connections through very strict firewalls, so if you are on a corporate network, try to get all participants to use Chrome or Opera. 
  • Interfering browser extensions: It is not uncommon for some third party extension to cause problems with some websites. To test this, try using your browser through an Incognito tab or Private browsing window. If all works normally then you know that an extension is causing an issue. Unfortunately there is no way to identify which one easily. A process of elimination will need to be done on each extension to fine the one causing the problem.
