I am a FreeDOS and other systems game programmer... but my games on FreeDOS do not have Sound yet. Are you using Allegro? I am using Freepascal... it is not Allegro friendly. I thanks for some Hint to sound on Freepascal... contact@juegosenlazaruscostatricenses.com
I have read a lot about sound blaster go32 djgpp Dpmi interrupts hardware interrupts. But it is not working yet.

My plan is recommend to use Freedos on Virtual box. So users will have some sound blaster emulation.
Very thanks, for your game... I like program on native DOS and next import to other systems. I think it is convenient , but people think I am wrong.
