I received my AMP 2 the other day and added it to my Raspberry Pi 3 B+ and I would like to know how to control the volume using the switch found in an Arcade1Up Cabinet.
The Switch is a simple slider with a 3 settings: mute volume, medium volume and high volume setting. it has three pins. (As you can see I'm sort of a layman with the Pi so far).
So far I have been successful in controlling the volume with the switch using the GPIO pins 6, 7 and 8 on the Raspberry Pi on its own after compiling some code I found online, However these pins don't adjust the volume with the AMP 2 connected.
Can anyone tell me if it is possible to control the volume of the AMP 2 with this simple switch?
