// This module handles dealing with generating sound on the appropriate

|
|
// Globals:
|
|
// For User Mgr:
|
|
// SoundBlasterPresent - SoundBlaster card present?
|
|
// AdLibPresent - AdLib card present?
|
|
// SoundMode - What device is used for sound effects
|
|
// (Use SM_SetSoundMode() to set)
|
|
// MusicMode - What device is used for music
|
|
// (Use SM_SetMusicMode() to set)
|
|
// DigiMode - What device is used for digitized sound effects
|
|
// (Use SM_SetDigiDevice() to set)
|
|
//
|
|
// For Cache Mgr:
|
|
// NeedsDigitized - load digitized sounds?
|
|
// NeedsMusic - load music?
