@ViRazY , Umm, I don't know what audio driver you are to get to work Windows Server 2019? I had no problem loading any Audio driver in Windows Server 2019 and 2022 as well.. So, I use Realtek HD Audio driver (using Windows 10 Drivers) and works just fine while I was testing Windows Server 2019 and 2022 base on x99 motherboard with LGA 2011v3 and has Realtek HD Audio and play back awesome..

Just use Manually install Windows 10 driver in the Windows Server 2019.. Should work, I tried on Realtek HD Audio on Windows Server 2022 STD no trouble with WIndows 10/11 Driver. ATGPUD2003
