C64s fails to detect soundcards

NOTE: Tested with C64s Shareware Version 2.52. Please use this specific version when testing.

Machine: Award 430VX
Video Card: Diamond Stealth 32
Sound Card: Sound Blaster 16
Dynamic Recompiler used, latest 64-bit build compiled from Git repository.

Extra info: C64s is an early Commodore 64 emulator for MS-DOS.

Starting up C64s 2.52 with the Sound Blaster 16 will result in soundcard detection fail, falling back to sound emulation via PC Speaker (which works suprisingly well with PCem's speaker emulation!) I tried Pro Audio Spectrum 16 and Gravis Ultrasound too, which appear to be supported by the emulator, but they don't appear to be detected too.

Can anyone log the way how this version detects sound cards by any chance?
