MS Teams does not find a microphone on my LG Gram laptop. Mic works in Zoom and other tools.

Good day @John Paul Jones, and I appreciate the clear explanation of your concern.  

Just to gently clarify before we go any further, this is a user‑to‑user support forum. I don’t have the ability to access or investigate individual accounts because this is a user-to-user support forum. Moderators and contributors, including external Microsoft employees, do not have access to internal systems or the ability to directly take action on Microsoft product features. However, I truly hope I can help review your situation, offer some guidance, and support you in finding the right next steps as best as possible.   

This type of issue is commonly related to microphone permissions, incorrect device selection in Teams, Windows sound settings, or audio driver problems.  

Please see the following workarounds that will help you verify the issue:  

Option 1: Try Teams on the web 

Open your browser and go to https://teams.microsoft.com/v2/  

Sign in with your account. 

When prompted, allow the browser to access your microphone. 

Go to Teams settings > Devices and test your microphone or join a meeting and try a test call. 

Option 2: Check microphone settings in Teams 

Ensure the correct input device is selected inside Teams. 

Open Microsoft Teams > Go to Settings > Devices 

Under Audio settings, check the Microphone dropdown. 

Select the correct microphone device. 

Click Make a test call to confirm your voice is detected. 

• If you are already in a meeting: 

Select the arrow next to the microphone icon. 

Choose More audio settings. 

Confirm the correct microphone is selected. 

Option 3: Verify microphone permissions in Windows 

Make sure Windows allows Teams to access the microphone. 

Open Windows Settings > Go to Privacy and security > Select Microphone. 

Turn on Microphone access. 

Turn on Let apps access your microphone. 

Make sure Microsoft Teams is enabled. 

Turn on Let desktop apps access your microphone. 

• If all options are already enabled: 

Turn them off. 

Turn them back on. 

Restart your device to apply changes. 

Option 4: Check Windows sound input settings 

Confirm that the microphone is detected and working at the system level. 

Open Windows Settings > Go to System, then Sound. 

Under Input, select your microphone. 

Ensure it is enabled and not muted. 

Speak and verify the input level responds. 

• If the microphone is not detected: 

Run the Input devices troubleshooter. 

Follow the on-screen instructions. 

Option 5: Update or reinstall the audio driver 

Driver issues can prevent the microphone from working correctly. 

Here are the steps to update driver: 

Select Start and search for Device Manager > Open Device Manager. 

Expand Audio inputs and outputs. 

Right click your microphone device > Properties > Select Update driver. 

Choose Search automatically for drivers. 

Follow the instructions and restart your PC. 

• If the issue persists: 

Right click the microphone device in Device Manager > Properties > Select Uninstall device. 

Restart your computer. 

Windows will reinstall the driver automatically. 

Option 6: Check for physical mute settings 

Some devices have a built-in mute control. 

Check your laptop keyboard for a mute key. 

Check your headset or external microphone for a mute button. 

Ensure the microphone is not muted at the hardware level.
