Assuming you are talking the same thing... But, I want to hold down a hot key, and push UP for volume increase and DOWN for volume decrease.

Thanks

i already told you how to for rpi. Are you using an encoder? The X in xbindkeys stands for x window system.

Post by: Maouu on November 02, 2016, 03:23:11 AM: I don't know if I use an encoder because I use a floob image which I downloaded on the attract mode website!
I boot directly under attract mode when I start my raspberry pi

Thanks you very much for your help!

Post by: YouBaxter on November 05, 2016, 11:11:44 PM: Okay...here is what I did...assuming you are wanting to do the same as me. . .

My Goal: Control volume by controlboard/controller/joystick.

Change: Modify the RetroPie JoyPad file

/opt/retropie/configs/all/retroarch-joypads
......Modify your controller file (backup first) (mine is snes30snes30joy.cfg for example)

Added the following lines to tie up and down DPAD Actions to volume increase/decrease.
input_volume_up_axis = -1
input_volume_down_axis = +1

This will map the action to your HOTKEY

I BELIEVE, you can also edit the "retroarch.cfg" file as well in the /opt/retropie/config/all directory, but I haven't modified that since the pi1 days.
