Teams couldn’t unmute (SOLVED)

During Teams meetings, I am sometimes unable to unmute my microphone:

It usually occurs when I use the Teams Web app ( 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:

control.exe mmsys.cpl,,1

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.

    Hi Tom! Seriously, this helped my alot. I have been using the teams web app since I’m using the local app for another organization. For some reason the webapp would always be on mute and I would end up restarting and being late to meetings. THIS solves everything! Thanks a million!

    This totally worked for me! I’ve been happily using the same headset, same browser(s) in Teams web and yesterday this problem started. Not sure how I muted to begin with, and I would never have found it so deep down. But it’s good now! Thanks so much!
