I’m interested in adding some physical volume buttons to my 2018 Picade. Adding the buttons is easy enough and I have no problems adding them to the hacker header on the Picade X HAT but what then… is there an easy way to make them control the volume (including when games are being played?).

Any suggestions welcome! Thanks!

I have absolutely no idea if it will work,but you could use the `gpio-key` dtoverlay and try these keycodes:

```auto
#define KEY_VOLUMEDOWN 114
#define KEY_VOLUMEUP 115

```
