Teams Mic is not working fine

Hi @Bhaskar Sankaranarayanan (ERNST AND YOUNG LLP),  

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

To assist you better, could you help me with the following:  

• Are you using a personal or a work or school account with Teams?  
• Are you checking via your microphone via “Make a test call” feature in Teams, or did another user report this issue? 
• Does the issue persist in the web version of Teams (via browser) or in the desktop app? 
• Does the issue occur in all calls, or only in specific ones?  
• Have you tested your microphone in other applications, and does it work normally there?  
• If you have access to another microphone, could you try using it in Teams to see if the issue is specific to your current microphone? 

  In the meantime, you can try the following steps and see if the issue persists:   

1. Clear the Teams Cache:   

This forces the Teams client to reload fresh meeting and app data.   

• For classic Teams:   

You need quit Teams completely (right-click the icon in the taskbar => Quit).   

Press Windows + R to open the Run dialog and then enter: %appdata%\Microsoft\Teams    

Delete all files and folders inside and restart Teams.   

• For new Teams:   

Type settings in the search box, and then select the Settings app from the results. 

Select Apps > Installed apps, and then type Microsoft Teams in the search box. 

Locate the New Microsoft Teams app from the results, select the More options button (...) on the right, and then select Advanced options. 

In the Reset section, select Reset. 

Restart Teams. 

1. Uninstall and Reinstall Teams:    

To uninstall Teams, you need to uninstall two items. Follow the steps below to fully uninstall Teams. 

• Quit Teams by right-clicking the Teams icon in the taskbar and choosing Close window. 
• In Windows, click on the Start button  , > Settings > Apps. 
• Under Apps & features, search "teams". 
• Highlight Microsoft Teams, then select Uninstall. 
• A box will appear, then again select Uninstall to confirm. A new box will appear, asking Do you want to allow this app to make changes to your device? Select Yes. 
• Now select Teams Machine-Wide Installer, click Uninstall. Then follow the same process described in the previous step 

Now you can reinstall Teams via this link: Download Microsoft Teams Desktop and Mobile Apps | Microsoft Teams
