We're running into this issue with ALL of our Optiplex 9020s after the Windows 10 1803 update. The RealTek driver (either from Dell or RealTek) will NOT install.  It errors out, either with a -0001 error, or a 0x0000374 error. The work-around, we've found, is to install the generic audio driver from Microsoft.  We've noticed no adverse effects from using this driver. Steps to do this in Windows 10: 1. Open the device manager 2. Find the Realtek HD Audio Controller (may be listed as an unknown device).  It will likely have a yellow triangle next to it. 3. Right-click on the device and select "Update Driver" 4. Select "Browser my computer for driver software" 5. Select "Let me pick from a list of available drivers on my computer" 6. In the next window, you may be prompted for the TYPE of device.  If you are, select "Sound, video and game controllers" 7. Ignore any RealTek drivers and select "High Definition Audio Device" and click NEXT. This will install the generic Microsoft audio drivers, which seem to work after the 1803 and 1809 updates.

I had this exact same issue with Dell U2717D monitors.  The monitors were mirrored and showed up in the display manager as one single monitor.  I played with enabling/disabling DP 1.2 on the second monitor to no effect.  Finally I found out that there was another setting in monitor configuration that was simply called "MST".  Evidently this is called "Multi-Stream Transport".  Once I ENABLED MST (in addition to DP 1.2) on the first monitor, the displays un-mirrored themselves and Windows treated them as separate monitors.  Enabling DP 1.2 and MST on the second monitor allowed me to daisy-chain a third monitor.  They are all recognized as 3 separate monitors and can have independent resolution settings.  At least for me, MST was the key.  The MST setting on the U2717D is under DISPLAY -> MST.  For me, at least, this fixed the issue of the displays mirroring while daisy-chained.
