Sound in DOS emulators
For DOS EMULATOR you should ALWAYS check for the SET BLASTER envirnment setting string in you autoexec.bat.
Type "SET" at the DOS prompt. If the Set BLASTER string is not listed add it just type "SET BLASTER=Axxx Iy Dz T4" where xxx is the Soundcard base addrees (normally 220), y is the Soundcard IRQ address (normally 5 or 7) and z is your Soundcard DMA address (normally 1). To know them you can check the settings in the Control Panel of Win9x by giving the CONTROL PANEL/SYSTEM/DEVICE MANAGER command, choose your Soundcard and clicking PROPRITIES/RESOURCES. A good idea is to add the string to the AUTOEXEC.BAT. Just run Notepad open autoexec.bat ( located in c:\) and add the "Set..." somewhere. Restart the computer. Once that done you will not need to check for the string again.
This imply that you have a Soundblaster compatible sound card.
This does not apply for emulaots which offer nativesupport for other soundcards such the Gravis Ultrasound or Ensoniq Soundscape....
