here comes the report..
I fixed the USB3 with a DSDT edit.
But Displayport Audio is not working. With Windows it works, so the cable is definitely ok.

Hi Guys,
I am trying to get Displayport Audio and USB3 to work on an Optiplex 9010. None of the DSDTs here seems to do the job with High Sierra - any ideas or any updated DSDTs available?
Cheers
Alex
