X240: No sound output via DisplayPort to HDMI cable

Hi,

I have a X240 Laptop (ThinkPad) - Type 20AMS05D00.

I connected an Asus monitor with integrated speakers to the mini displayport with an mini displayport to hdmi adapter.

I'm using windows 10.

 

The display is shown good, but i can't get any sound output...

The external device is not listed in the device manager and not in the playback device section (right click on sound symbol in the bottom right corner).

At this moment i tried to turn it off and on again..., uninstall audio drivers, check if there are new drivers with lenovo update tool, updated all other drivers and restarted the windows audio service (it was running).

 

When i change to Ubuntu 14.04 the sound output is working fine! So i think it should be a driver problem.

Are there any solutions for this?
