Dear Nicolò De Laurentis,
Welcome to the Microsoft Community
It seems like you’ve gone through a comprehensive troubleshooting process already. Given that the Bluetooth devices work correctly on a different machine and that you’ve tried multiple drivers and even a clean installation of Windows, the issue might indeed be related to the latest Windows 11 24H2 update or potentially a driver/hardware conflict specific to your motherboard on this version.
Here’s a more structured approach to resolve the Bluetooth issue:
Step 1: Update Windows
Ensure that your Windows 11 24H2 is completely up-to-date. Sometimes Microsoft releases patches to fix such issues.
Press Win + I to open Settings > Windows Update > Check for updates.
Step 2: Update BIOS and Firmware
Since your motherboard is relatively new, ensure that the BIOS and firmware are up to date. Asus regularly updates their BIOS to include better hardware compatibility and bug fixes.
Visit the Asus support page for your motherboard.
Download the latest BIOS update and follow the instructions provided by Asus to update your BIOS.

Step 3: Check and Reinstall Bluetooth Drivers
You mentioned trying different drivers, but it’s worth a second look.
Press Win + X and select Device Manager.
Expand Bluetooth, right-click your Bluetooth adapter, and select Uninstall device.
In the confirmation dialog, check Delete the driver software for this device and click Uninstall.
Visit the Asus support page and download the latest Bluetooth drivers for your motherboard.
Step 4: Adjust Bluetooth Signal Settings
Press Win + X and select Device Manager.
Expand Bluetooth, right-click your Bluetooth adapter, and select Properties.
Go to the Power Management tab and uncheck Allow the computer to turn off this device to save power.
Ensure that there are no physical obstructions or electronic interference near the Bluetooth adapter. USB 3.0 devices and ports, other electronics, and even certain wireless devices could potentially interfere.
Step 5: Check Bluetooth Services
Press Win + R, type services.msc, and press Enter.
Ensure that the following services are running and set to Automatic:
Bluetooth Audio Gateway Service
Bluetooth Support Service
Bluetooth User Support Service_XXXXXX (where XXXXXX can be a part of your computer name).
Step 6: Checking if your Windows 11 PC supports LE Audio
Select Start> Settings> Bluetooth & devices.
Select Devices.
Scroll to the Device settings section.
Look for the presence of a setting titled Use LE Audio when available. Ensure this setting is turned Off. If this setting is not available, your PC does not currently support LE Audio.
Potential Workaround with a Bluetooth Dongle
If after all these steps it still doesn't work, you can try using an external Bluetooth USB dongle to bypass the internal Bluetooth adapter temporarily.
Obtain a USB Bluetooth adapter (make sure it's Bluetooth 5.0 or higher) and plug it into your desktop.
Install any necessary drivers and try connecting your Bluetooth devices through this dongle.
If after all these thorough steps the issue still persists, it might indeed be a bug introduced in the 24H2 update. In that case, you could consider providing feedback to Windows Dev teams.
Press Windows + F to open Feedback app > Give new feedback. The development team regularly reviews submitted feedback and provides fixes. Please be patient and wait for a system update, which will usually provide an update package to fix the problem.
Feel free to reach out if you have any further questions or need additional help!
