Hello, I have a Picade based on MAME and Attract Mode only installed on a standard Bookworm Lite. It works perfectly. I can also manage the sound level from the terminal using the alsamixer command. But I can’t manage it directly from Attract Mode or Mame. I would like to assing Volume with the Button 1 (Left control) + Joystick Up to increase the volume and Btn1+Joy Down to decrease. I tried using the bind or trap command executed from a background service but it doesn’t work. Is there anyone who made this possible with bookworm lite without retropie or an other embedded system. Any help would be greatly appreciated.
