Hello,
- Do you have another pair of headphones? If so, please connect them to the device and check whether they work. This will help determine whether the issue is with the current headphones.
- Do the headphones you’re currently using work normally with another device?
Meanwhile,
Unplug the headphones connected to your device.
- Then, go to Device Manager.
- Expand the arrow next to Sound, video and game controllers.
- Right-click your default audio output device, such as Realtek (R), and select 'Disable device'.
- Wait for a few minutes, then right-click and enable the device again.
- Plug in the headphones and test to see if they work.
If you are still having issues,
- Unplug your headphones,
- then right-click the default audio output device, select Uninstall device, select the 'Attempt to delete the driver software for this device' checkbox, and then click Uninstall.
- Once uninstalled, restart your computer, then plug in your headphones to see if they work.
