4.5.2 Audio Playback Demo

To run the audio playback demo, create a script that acts like the following.

#!/bin/sh
while [ 1 ]; do
    arecord -Dplughw:0,0 | aplay -Dplughw:0,0
done
And then you can run the script with the following command.

root@am62lxx-evm:~# ./<Audio Script>.sh
Use Ctrl + C to end the script execution.
