I recently bought a Flex 2-14 with Windows 8.1 installed and upgraded it to Windows 10 (Education Version). I haven't tried the sound on the 8.1 system - directly upgraded to Windows 10.
When I plug in headphones, the notebook doesn't recognize them. When I unmute/mute using the F1 keys sound comes through the headphone - terrible quality, though. When I change the volume using the F2/F3 keys that switches it back to the loud speakers and so on.
It seems to me that the laptop doesn't recognize the headphones at all. When I look into the sound devices in the taskbar, there aren't any headphones listed.
Failed attempts to solve the problem:
Updating the drivers from the Lenovo website.
Updating drivers from Realtek directly.
Sleeping/waking the notebook.
Turning off the multichannel option with the Realtek HD Audio-Manager.
I think that's pretty much all I've tried so far.
Most of the times the problem just stayed the same. Sometimes it wouldn't switch back to the speaker when pressing the F1/F2/F3 keys, but that is all that my attempts changed so far.
I'm thankful for any hints!

Hi there, Mabreidi -
Thank you for writing in to the Lenovo Forum - happy to have you here today.
There is usually a hardware switch in the socket, which is engaged when you put the plug in. Seems like it might be mechanically broken.
I would recommend contacting Lenovo service centres and applying the normal phone techniques to get it replaced promptly or assist you further.
