Try this example, let me know if it works.

# include "alt_up_audio.h"

// assumes input only from right channel

int main()

{

unsigned sample_count;

long audiobuf[128];

alt_up_audio_reset_audio_core(); //get the audio started

while (1)

{

sample_count = alt_up_audio_read_right_channel(audiobuf,128);

if(sample_count)

{ //must write both output channels

alt_up_audio_write_left_channel(audiobuf,sample_count);

alt_up_audio_write_right_channel(audiobuf,sample_count);

}

}

}
