Camera and mic locked in Teams. How can I turn them on again?

Hello @Mim,

Thank you for reaching out to the Microsoft Q&A forum. 

Based on the description and the screenshot you shared, I understand that you are currently experiencing an issue while setting up audio in Microsoft Teams on the web. I know how frustrating it can be when audio settings do not work as expected, especially when you are trying to join or participate in a meeting, so I want to make sure I guide you through a few steps that may help resolve the problem. 

To begin, I recommend checking your browser’s site permissions to ensure that the microphone is allowed for Microsoft Teams: 

For Google Chrome: 

• Open the Menu (⋮). 
• Go to Settings → Privacy and security → Site settings. 
• From there, scroll down to the audio section and make sure the correct microphone device is selected and allowed. 

Note: Microsoft is providing this information as a convenience to you. The site (Google Chrome) is not controlled by Microsoft. Microsoft cannot make any representations regarding the quality, safety, or suitability of any software or information found there. Please make sure that you completely understand the risk before retrieving any suggestions

For Microsoft Edge: 

• Select the Menu (⋮). 
• Go to Settings → Privacy, search, and services → Site permissions. 
• Under the audio section, choose the correct device and adjust the permissions as needed. 

In addition to checking browser permissions, I also recommend trying Microsoft Teams using the desktop application. This helps me confirm whether the issue is related to the browser or if it affects Teams across different platforms. Sometimes the desktop app handles device recognition more consistently. 

I also suggest testing a different headset or audio device, as well as making sure that the audio drivers on my computer are up to date. Outdated or incompatible drivers can cause unexpected behavior in Teams or other communication tools. 

For more detailed troubleshooting steps, I can also refer to the following Microsoft support article:  Fix sound or audio problems in Windows - Microsoft Support 

If you need any additional assistance, please feel free to let me know. I am looking forward to hearing back from you and helping you further with this issue.
