Hi I am currently trying to moddify the react-carplay code with a new ui and more fonctionnalities to make a carplay powered radio for my car. This would use a rpi5 and right now what im trying to do is to have 3 buttons to control the volume/mute/unmute of the rpi but all modules that i found like loudness or volume-suppervisor or another one that i cant remember all require child_process which was removed from npm and github so I cant use those
How can I change the system volume in my project ?
