These work too:
Actually the only drivers which seem to work are the two links from Intel. I'm pretty sure nothing from Realtek worked.
that's because the latest available Realtek HDA drivers from the Realtek web site are from late July 2017 and are only compatible up to Win10 RS2 (creators update) and are in standard HDA (nonUAD/nonDCH) format instead of the newer & smaller UAD/DCH format
while the two Realtek driver links from the Intel site you mentioned are on UAD/DCH format but also bundle the bloated Intel HDA bus driver for SST (SST = sound state technology)
UAD = universal audio driver
DCH = declarative componentized hardware
