Thank you very much! ?
I’ll copy my own SC installation to my phone to double check, will take a while to dl it from my cloud storage.
But I’m seeing a possible reason: you said you’ve configured Windows to use Soundblaster 16, but you’ve set sbtype=sb2 in your conf settings. So I’d suggest you change that to sbtype=sb16, and oplmode=auto.
As a general suggestion, unless you have an older phone/tablet, you should also set rate=44100 (under the [mixer] tab). This has practically no impact on performance, but wildramatically improve the quality of General MIDI and MT32 emulation.
