Windows 10: audio not working after 2004 update on ms surface pro 7, driver missing

My Surface pro 7 had the Windows 2004 update applied yesterday.

Afterwards the audio stopped working.


The troubleshooter thinks that a restart is needed, but I have restarted several times.


The only drivers visible are for a mobile device.


The audio services are running.

Scan for hardware changes does nothing.

Is it possible to get the Surface to recognise that the drives are missing?

MS Surface Keyboard Cover not recognized by MS Surface Pro 3

My Surface Pro 3 cover mysteriously stopped working (other USB keyboards work).

I’ve exhausted all of the steps from the Internet and am hoping for some advice here on what to try next.

• Clean the metal pins on both the keyboard and the Surface Pro 3 with alcohol swap and q-tip.
  
• Performed the standard two button shutdown procedure - https://support.microsoft.com/en-us/help/4036280/surface-force-a-shut-down-and-restart-your-surface
  
• Update "HID keyboard" device in Device Manager.
  
• Uninstall and reinstall "HID keyboard device" in Device Manager.
  
• Removed HID keyboard device in Device Driver and manually installed Surface Type Cover device (which later automatically turns to "HID keyboard device" when you hit "update drivers")
  
• Updated all Windows 10 patches to date.
  
• Tried a brand new keyboard (Microsoft FMM-00001 Type Cover for Surface Pro https://www.amazon.com/gp/product/B073W4MPJF/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 )
  
• Updated firmware for Surface Pro 3 (typed in “winver”, took that Windows version, then downloaded the specific patch required here - Download Surface Pro 3 from Official Microsoft Download Center)
  
• Reset Surface Pro 3 while keeping personal files
  
• Reset Surface Pro 3 and deleted all personal files
  
• Performed hardware tests on aka.ms/surfacerepair (nothing bad found; all looks ok)
  
• Drained the battery most of the way before connecting again - the two times it worked momentarily these last few days was when I connected my new type cover keyboard to the Surface Pro 3 after the battery had died down to below 50%; a simple reboot later, everything stopped working. This user seems to have the same problem with it working briefly when there is low battery - Surface Pro 3 Battery drain along with type cover connector failure )
  

A breakdown of the steps I've done to sometimes get it working

• Leave Surface Pro 3 on about 2 hours on battery only.
  
• Power on Surface Pro 3.
  
• Working Keyboard.
  
• Turn off Surface Pro 3 (or reboot)
  
• Keyboard not working anymore
  
• Another similar user here - Surface 3 type cover issue
  

Can anyone recommend any other troubleshooting steps? One of these steps seemed to work ok for others having this same problem.
