- initialize the audio device (LOCAL)

SYNOPSIS

int init_audio ()

ARGUMENTS

None.

RETURNS

TRUE in case of an error, FALSE if succesful.

FUNCTION

Opens the audio device /dev/audio write-only, checks whether it is the correct device (AMD) and initializes the device (sample rate = 8000, channels = 1, precision = 8, encoding = AUDIO_ENCODING_ULAW, gain = 128, port = AUDIO_SPEAKER). For an explanation of these constants, see the include-file sun/audioio.h. The routine sets the fdaudio file descriptor (see SOUND-variables).

NOTE

The sound generation functions only work on Sun workstations running SunOS and containing an AMD-AM79C30A sound controller chip. This function is used by the sound_sample routine.
