Hi LR_112,
Thank you for reaching Microsoft Community. We appreciate for sharing your concern to us.
Would you mind telling me the brand and model of the Bluetooth speaker you want to connect?
Have you tried to connect your Surface device with other Bluetooth accessories? Does it still have the same problem?
You may try the following steps to troubleshoot the issue.
Check Windows Updates including optional updates if available and install them.
Go to Settings >> Update and Security >> Windows updates >> Check for updates.
Run the Bluetooth Troubleshooter.
Select Start, then select Settings > Update & Security > Troubleshoot. In Find and fix other problems, select Bluetooth, and then select Run the troubleshooter and follow the instructions.
If your Bluetooth device displays as Pairedin Settings > Bluetooth & devices > Devices, but you can’t hear audio, make sure it’s connected. In Devices, select More options next to the device, and then select Connect.
Make sure the audio device is within range of your PC. Check to see if any other devices are linked to the Bluetooth speaker. If the speaker is connected to other devices through Bluetooth, you can disable it.
Make sure the audio is playing through the Bluetooth device. Select Start > Settings > System > Sound. Select Choose where to play sound then select the Bluetooth device.
Update Bluetooth driver.
- In the search box on the taskbar, search for Device Manager, and then select Device Managerfrom the list of results.
- In Device Manager, select Bluetooth, and then select the Bluetooth adapter name, which may include the word “radio.”
- Press and hold (or right-click) the Bluetooth adapter, and then select Update driver > Search automatically for updated driver software. Follow the steps, then select Close.
- After installing the updated driver, select the Start button, select Power > Restart if you're prompted to restart, and then check whether that fixes the connection issue.
Uninstall Bluetooth adapter.
- In the search box on the taskbar, enter device manager, then select Device Managerfrom the results.
- In Device Manager, select Bluetooth. Press and hold (or right-click) the Bluetooth adapter name (which may include the word “radio”), and select Uninstall device.
- Select Start, then select Power > Shut down.
- After your device shuts down, wait a few seconds, and then turn it back on. Windows will try to reinstall the driver.
- If Windows doesn't reinstall the driver automatically, open Device Manager and select Action > Scan for hardware changes.
Let me know how it goes.
Kind regards,
