Hello Audio

This demo just demonstrates audio output. It plays a sine wave, which makes a kind of 'WOO WOO WOO' sound.

cd ..
cd hello_audio
ls

Notice the green .bin file? Run it. Are you getting the hang of this now?

./hello_audio.bin

This will play the sound over the headphone jack on the Pi. If you're using a HDMI monitor you can make it output over HDMI by adding a 1 to the command:

./hello_audio.bin 1

The demo will run forever until you quit. To exit the demo press Ctrl + C.
