Not an issue but, volume control

[JeromeL63]

Hello,
Is there a way to deamonize bin/speaker_controller_application? I tried to make a .service file but no luke.
speaker controller, make good job. When launch in a terminal, I can vol + vol - with my smartphone.
if I try to launch by ./speaker_controller_application &, nothing happen :'(

I can only run it to and cannot use it as service.
I can see something being registered on the pi terminal when I press volume up/down on my phone.
but it doesn't actually change the volume. I'm wondering why.

those random characters show up when I press volume up/down but it doesn't actually change the volume.

I'm running this on a volumio OS.
