Hi,
Thank you for writing to Microsoft Community Forums.
I understand how difficult it is, when the device doesn't work in the way it should. For us to isolate the issue and to assist you better, we'd like to ask you a few questions.
- What is the make and the model number of the computer?
- What is the make and the model number of the headphone?
- Are the speakers muted when the headphone is plugged in?
- Are you aware of any changes made on the computer prior to this issue?
We can try a few steps and check if we can fix this.
Method 1: Remove and connect the Bluetooth headphone and check.
- Press Windows key + I together to open Settings.
- Click on Devices > Bluetooth & other devices.
- Now click on the Bluetooth headphone and click on Remove device.
- Turn off Bluetooth and the headphone and turn them back on, and Connect.
If the issue persists, try method 2.
Method 2: Enable the Bluetooth headphone.
- Right click on the Volume icon on the taskbar.
- Click on Sounds.
- Navigate to Playback tab.
- Right click on an empty space and select Show Disabled Devices.
- Check if the Bluetooth headset is showing in the list.
- Right click on the Bluetooth headphone and click Enable and check.
If the issue persists, I'd suggest you to refer this article on Fix sound problems in Windows 10 and try the suggestions showing under the Run the audio troubleshooter, Fix your audio driver, Set default device, and Turn off Audio Enhancements section and update us on the result.
We'll be waiting for your response.
