Windows 10: Speakers have sound but headphones do not...

Since yesterday I have lost sound to my headphones on my Thinkpad 540p. The speakers work fine and they mute when the headphones are plugged in. I have tried another pair of headphones with similar result. I have spent the afternoon following advice here and on search engines without success. I have uninstalled and reinstalled the Realtek drivers, run the troubleshooter, changed sound formats all to no avail. It seems my headphones are not seen by W10. When I go to Manage Sound Devices only the speakers are shown, no headphones (which are plugged in). Listing hidden devices is enabled. I cannot think of anything more to do so I'd be glad of some advice how I can proceed further, please.
Windows 10 64 bit version 2004.

No sound from headphones but speakers work.

No Its Just A Speaker

 

No sound from speakers/headphones

Disconnect the front panel headphone/mic jacks from the motherboard and then see if the rear panel GREEN speaker jack works (either with speakers or headset). This is in case the front panel jack is causing no audio out. Power off the PC before opening and disconnecting the front panel audio.

The connector for the front panel audio is listed as #21 on the motherboard drawing (below).

 

How do I combine both my speakers and headphones? Can't have both?

Hi Emma,

Thank you for posting your query in Microsoft Community.

• 
  Are u using inbuilt sound or do you have a sound card installed?
  
• 
  Have you installed all the latest drivers for the motherboard after upgrading to windows 10?
  

By default Windows switches the sound when we insert the headphones and automatically moves to speakers when headphones are taken out.

I suggest to follow the steps from this article and check if it helps:
