Let's install it

- 40pins header is already soldered! but still we added long pin so you can still add other shields on top

For Raspian users (works also for Retropie):

-Insert your Rapsberry Pi Audio Shield in your Raspberry pI then turn it on

-Make sure your audio jack is plugged in to your amplifier

-Open a terminal (yes the black windows thing) and type:

sudo wget -O - script.raspiaudio.com | bash

-say yes for the reboot

-If everything went fine you should here a test sound when tryping this command:

sudo speaker-test -l5 -c2 -t wav

-NEW! : On the next reboot you will be able to control the volume from your desktop or by using the line command tool alsamixer

For references here is the script source.
