Installing GUS for DOS requires a lot of tweaking to get it to work. On Windows, it’s even more of a pain. If you’re interested, there’s a step-by-step tutorial on Vogon. But that doesn’t solve the problem. The game might not even start.
I’m confusing things, it’s not EAX (it came out with SB Live). An Alpha Centuri developer said that the problem lies in the soundround. The eax=0 in the .ini file is from the later update.
The SB16 is compatible with Qsound and A3D, both of which produce reverberation effects, and all games are related to this effect, such as in NFS2 when you drive through the tunnel, the audio is turned off. If this is the problem, it may be very easy to fix.
I don’t know, maybe there is a specific list for DOSBox. It has two particularities: they are compatible with Windows 95 and SB16.
The closest thing I found is this list of Windows games with Soundround on mobygames. It might be a good place to start.
