Any particular game? IF I have it I can try it on my win 3.1 machine.

I'm looking at games like Biomenace, Keen, Monkey Island, Wolf3D. The classics. Maybe you'll have better luck @Robbbert ?

I'm using Windows for Workgroups 3.11, but apart from the networking facility it's much the same as Windows 3.1 .

Tried Wolf3D, Duke Nukem 1 and 2, crystal caves, secret agent man and some other early Apogee games, and they all worked with sound from within windows. Also tried Hocus Focus, but the keyboard stopped working although the music played.

It's not actually recommended to play DOS games from within Windows because of possible instabilities and slowdowns. Using Windows 98SE is a *much* better proposition. Despite that, there's lots of DOS games that do work well inside Windows 3.1 .

Make sure to set your BLASTER variable inside your autoexec.bat, and (at least in theory) you shouldn't have any problem.

If you've got a Pro Audio Spectrum 16, then merely the native part is being under Windows control by the supplied driver.
The optional Soumd Blaster emulation for legacy software isn't being affected, afaik.
And OPL3 can be manually controlled by DOS applications, Windows (Voyetra driver) and Windows applications.

In essence, it's like with 32-Bit OS/2. You've got two separate DACs/ADCs.
One for OS/2 and one for Win-OS/2 environment.

Speaking of.. There's a GENAUD driver for Win-OS/2, because there's a similar issue in sharing the sound devices under OS/2.
Maybe it works with real Windows 3.1, too, not sure.

Cheers guys I'll do more testing in a few days, sounds like it's possible which is awesome!
