If you have followed the process in the
Determine the HDA Realtek driver needed for your Audio - Windows 10 Forums post and you found that you need a driver with "Fortemedia (FMAPO) Integration", it means that you have the old legacy HDA drivers installed, as these type of drivers are detected by this process!
The above Windows Update Catalog extract shows the new UAD drivers (judging by their small file size, 9.5-9.9 MB),
except from the first entry, which seems like an HDA driver.
So the only one that might work for you is the 1st one, but you have to open the cab file, with 7zip, and look for the integration contained, based on the "special" files presented in the aforementioned process you followed to determine your FMAPO integaration.
Most likely it does not contain your audio device's HardwareID in its .inf files, nor the FMAPO integration "special" files, so it cannot be installed.
Skip it and if you want to upgrade, go to the
Alanfox2000 github and download the latest HDA driver, which contains your FMAPO integration. The file name you look for, in that site, should be like something
8xxx_FF0C_FF00_FF01_FF03_FF04_FF06_FF10_PG471_Win10_RS3_RS4_RS5_19H1_Win7_WHQL.rar
where 8xxx is the driver version, i.e 8678, 8688, 8694 etc.
Once you download and extract the file, go to its FF01 (Fortemedia) folder and install the new driver, either by using the setup included or by going to Device Manager, to your Realtek audio device, open its properties and update the driver by selecting to look for the update in the FF01 folder of the extracted file.
