All bluetooth headset mic is not working with Window 11

Dear @Timothy Liew,

First, I want to sincerely apologize for the frustration this issue has caused. We understand how important your headset is for daily work, and we truly appreciate your patience while we work through this together.

We’ve seen similar cases recently after Windows 11 updates, and while we’re doing everything we can to assist, this may require deeper troubleshooting with Microsoft Support to ensure a permanent fix.

Therefore, could you please try the following steps so we can narrow down the issue?

1/ Confirm your headset model

• What is the exact brand and model of your Bluetooth headset?
• Do you have more than one headset, and does the issue occur on all of them?
• Does the headset microphone work correctly when paired with another device (e.g., phone or tablet)?
• Which Windows 11 version and build are you currently running? (For example: Windows 11 Home or Window 11 Pro)
  • You can check this by pressing Win + R, typing winver, and sharing the version and build number. For Microsoft's instruction: What version of Windows am I running?
  • If possible, please provide a screenshot to help us diagnose the issue more effectively.  

2/ Test the microphone in Windows

• Go to Settings > System > Sound > Input.
• Select your Bluetooth headset and check if the input level bar moves when you speak.

3/ Test the microphone in Microsoft Teams

• Open Teams, go to Settings > Devices, and select your Bluetooth headset as the microphone.
• Use the Make a test call option to confirm if it works.

Moreover, here are some additional steps I recommend you try:

Step 1/ Create a New Windows User Profile Sometimes profile corruption after an update can cause audio issues. Please create a new local user account and test the headset there. (Settings > Accounts > Other users > Add account)

Please follow the Microsoft instruction here*:* Manage User Accounts in Windows

If It Works in the New Profile This suggests the issue is tied to your current profile, likely due to the recent Windows update.

Step 2/ Revert to Previous Windows Version (Optional)

If you've recently installed a Windows Update and the update is causing your device to have errors or other issues, uninstall the update to try to resolve the issue. Please follow the Microsoft Official Guide here: How to uninstall a Windows Update

__Important: __Before uninstalling a security update, make sure you understand the risks. If you're using Windows 11, try to reinstall your version of Windows first.

These steps help us confirm whether the issue is with Windows, the headset, or the app. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this.

Note: Please understand that as forum moderator, I don’t have access to the backend systems to troubleshoot this effectively due to privacy and security constraints. I am just organizing use cases and collecting data, including from you, on a daily basis and will continue to monitor the progress of this issue.

Thank you for your patience and your understanding. If you have any difficulty, please feel free to reach out.

I'm looking forward for your reply.

This stopped working a few days ago. It worked for 2 months. The headset works on other devices. When you select headset for mic in an app the speaker just clicks. One time it rebooted the machine. I need these for work. I tried another headset and the same issue.

I ran Audio and Bluetooth troubleshooter, and it seemed to fix the issue. Just leaving this for others to try.

Dear @Timothy Liew,

Because the problem persists after trying all the above troubleshooting steps, the fastest and most effective way to resolve this is to work directly with Microsoft Support. They have the tools and resources to perform deeper diagnostics and apply advanced fixes for Bluetooth and audio issues, especially those caused by recent Windows updates.

Note: Please be reassured that you are not alone, I’ll continue to monitor this case and will reach out to you with any new updates as soon as possible.
