Headphones not showing up in playback devices
The problem could be with the headphone, headphone port, or the system. Now if the problem is with the hardware, you might need to replace the components. But it would be advisable to try the following troubleshooting before replacing anything. I would suggest the first step as changing the headphone port; however, most computers wouldn’t have an extra port for headphones. If your computer has one, try it. Then, try to connect your headphone to a different system and check if it works. This is to isolate whether the problem is with the system or the headphone. If the headphone works, proceed with the following troubleshooting sequentially to resolve the issue.
1] Run the Playing Audio troubleshooter
The Playing Audio troubleshooter will check all problems related to audio playback. Then it would either resolve the problem it at least list it so you could fix it manually. The procedure to run the Playing Audio troubleshooter is as follows:
Windows 10: Click on the Start button and go to Settings > Updates and Security > Troubleshoot. Select the Playing Audio troubleshooter from the list and run it.Windows 11: Click on the Start button and go to Settings > System > Troubleshoot. Select the Playing Audio troubleshooter from the list and run it.
Restart the system.
2] Update the Audio driver
Many headphones have drivers, and many don’t. So if you don’t find a driver for your headphone, don’t panic. My system doesn’t have one either. The procedure to update the drivers is as follows: Press Win+R to open the Run window and type the command devmgmt.msc. Press Enter to open the Device Manager window. In the Device Manager window, expand the list for Audio inputs and outputs drivers. Check if you find a driver associated with your headphone in the list. You could also eject and replug the headphone to check if a driver pops up there. If you find a driver, right-click on it and select Update driver. If you don’t find any driver, check the headphone manufacturer’s website for one and download that driver.
3] Enable the headphones from the playback devices
Press Win+R to open the Run window and type the command mmsys.cpl. Hit Enter to open Playback devices. Right-click anywhere in the open space and check the boxes for Show Disconnected Devices and Show Disabled Devices. This could help display your headphone/s in the Playback devices section. You can right-click and Enable them if they are disabled. Hope something helps.
