Lenovo x250 realtek sound controller cant find external sound devices!

Hello Guys! 

 

At my workplace we are experiencing with ALL  our x250's that the internal Realtek Sound Controller cant transfer sound to external devices, only picture. 

 

In Device Manage -> System units, I can see that is detects the external input as "High Definition Audio-controller" but has a little warning triangle with an exclamation mark, and you cant select other speakers under sound (in the processbar) except from the build in speakers. 

 

We have tried using all sorts of externalspeakers incl. mini-jack input, but nothing works. 

 

Info:

Model: Lenovo x250

Win: Windows10 1803 build 17134.376

Realtek High Definition Audio (controller) driver vers. 6.0.1.8409    17 Apr 2018 (newest version for 1803)

Connection: MiniDisplay-port 

 

I really really hope someone in this forum can help with this problem, as it affect alot of colleagues not being able to play sound on our projectors.
