how to make volume up and volume down with buttons

@caver01 Sir,
first of all thanks for the trick! I have two player usb encoder setup. Whatever i did unable to figure out to ran the volume up and down command over GPIO on raspberry pi or from on my joyistic buttons.
Would you please share with us in here your used python or shell script or whatever using to up and down the volume with buttons.Thanks

Sorry, I am not near my system to share a config, and at this point I don't even remember how or where to find a config. I simply followed the instructions to setup the software, then added commands via the web interface using the GPIO pins I know I am using.

I will add that for a second go-round on a NESPi setup, I simply wrote a Python script to manage GPIO inputs watching for EDGE triggers, then executing commands. If I could do over again, I would not need to use something with the fancy setup and web interface like GPIOnext. Raw Python would work fine.

I have figured out an easy way to change the volume within retroarch configuration. Yes, you will need a game loaded in order to change the volume and this only applies to emulators managed by retroarch but I find it is the best way for me to change the volume in my small arcade cabinet and also my Game Boy zero build.

I recorded the process but it is as follows:

RetroPie --> retroarch --> Main Menu --> Settings --> Input --> Hotkey binds

Then just make sure your binds dont clash with any existing ones, set the control for volume i.e. left/right and save the configuration before quitting retroarch.

In game you will be able to control the volume with your controls whilst holding the hotkey (select if you dont have a dedicated hotkey).

@fredbuilder This was discussed earlier in this thread, but via direct editing of the config file. Thanks for the addition about the GUI and for the video. Nice handheld. 🤩
