Microsoft Update Catalog
Search results for "Realtek Audio Device Windows 10"
Click on the "Last Updated" column title to GET the newest release at the top of the list. At the time of this post, it's 6.0.1.8678.
Click on "Download". Microsoft will offer you a CAB file with a ridiculously long name; Save it to your PC. Note: I recommend renaming the CAB to something a Bit more memorable like "Realtek Audio 6.0.1.8678 UAD".
Unpack the CAB file (I used 7-ZIP for this, but many other archive programs can also handle CAB files).
Launch Device Manager.
Expand the "Software components" category and make sure the 3 items are there (see erpguy53's screen shot in post #2).
Expand the "Sound, video and Game controllers" category. Right-Click on "Realtek(R) Audio", select "Update driver", then select "Browse MY Computer for driver software". Point Windows to the location where you unpacked the Microsoft Update Catalog CAB file.
Reboot if prompted.
