install_sound_input - Initialises the sound recorder module. Allegro game
programming library.
#include <allegro.h>
int install_sound_input(int digi, int midi);
Initialises the sound recorder module. You must install the normal sound
playback system before calling this routine. The two card parameters should
use the same constants as install_sound(), including DIGI_NONE and MIDI_NONE
to disable parts of the module, or DIGI_AUTODETECT and MIDI_AUTODETECT to
guess the hardware.
This function returns zero on success, and any other value if the machine or
driver doesn't support sound recording.
