The version from GitHub (1.0beta4) works. Tested in pure MS-DOS 6.22 on YMF754 in Z.A.R. with the /t6 parameter (SoundBlaster16) in 44kHz, 16-bit, Stereo mode. There are no complaints. I also checked Quake 1.06 without the /t6 parameter (Default settings) - it also works fine. System board based on …

Also what version of Doom are you using? I've only used Ultimate Doom with sbemu. But usually Doom, Duke3d, Quake, and Wolf3d work mostly fine. It's the deeper dos library that can get problematic. Have you tried using a different irq and dma? Although strange that Quake works fine. Maybe Crazii …

You may want to try an earlier version too. Also, maybe try the freedos bootdisk in case it's related …

The latest build works great on my Dell Latitude D600 laptop, which is an ICH4 chip I think? I have noticed in Doom shareware that the sound FX start getting choppy around level 2 or 3. Has this been discussed before? It's pretty amazing software though!
