蓝牙耳机连上电脑后，麦克风有显示，但是无法使用是什么情况

Hi Jacky,

Based on recent reports, there appears to be a compatibility issue between Windows 11 24H2 and certain audio drivers—particularly those using Intel Smart Sound Technology (SST). This can impact both internal and external microphones, as well as Bluetooth audio devices2. Users have noted missing audio enhancement options and extremely low or non-functional microphone input following the update.

Here are a few steps you can try to improve functionality:

1. Check for Updated Drivers: Visit Lenovo’s support site and install the latest Bluetooth and audio drivers specifically validated for Windows 11 24H2.
2. Disable Audio Enhancements: Go to Settings > System > Sound > Input, select your microphone, and disable any enhancements if available.
3. Use the Troubleshooter: Navigate to Settings > System > Troubleshoot > Other troubleshooters, and run both the Bluetooth and Recording Audio troubleshooters.
4. Roll Back to 23H2 (if critical): Some users have found that reverting to Windows 11 version 23H2 restores full audio functionality. If this is a viable option for your environment, it may serve as a temporary workaround until a patch is released.

T&B, Harry.
