During Teams meetings, I am sometimes unable to unmute my microphone:
It usually occurs when I use the Teams Web app (https://teams.microsoft.com) and Bluetooth headsets that mute when I raise the microphone arm.
If I am on my Lenovo laptop, I can usually solve it by using the function key for microphone mute/unmute:
But on my desktop computer’s keyboard, I do not have that key.
To solve it, I right-click the volume icon in the system tray and select Sounds:
Click on the Recording tab, select the microphone you want to unmute and click Properties:
Click on the Levels tab. Here I can see that my microphone is muted in my computer’s sound settings (just as Teams said):
Click on that icon to unmute:
Remember to lower the microphone arm on your headset if you have automatic mute when it is raised.
The mute symbol is gone, and I am automatically unmuted in the Teams meeting, yay!
You can go directly to the Recording tab in Sound settings using this command:
I have created a shortcut on my desktop for this for quick access:
Please comment and let me know if this solved it for you or not. I can update this post with other solutions you may have.
Also, let me know if you have more information about why the microphone is muted in Windows in a way so that Teams or my headset cannot unmute it.
The free tool SoundVolumeView from NirSoft solves this in a fantastic way! You can download it here:
It does not require any installation, just download it, extract the zip file, and run the app called SoundVolumeView.exe. Select the microphone you are using and Press F8 (or right-click) to unmute:
Even better, you can easily create a Desktop Shortcut to specific actions. Here I chose to create a shortcut to toggle the mute status on my headset’s microphone:
Now I can just double-click this icon on my Desktop to unmute:
Another thing, the is a global microphone mute/unmute button coming to the taskbar in Windows 11, that may solve this issue without third party apps. Here is a 7 sec video of how it will look:
