A node.js library to control the systems output volume fork from https://github.com/LinusU/node-loudness. added hazardous package for electron, fixed that the electron app can't find the correct path which in the "app.asar.unpacked" folder.
The library currently has support for four simple async functions. The volume is specified as an integer between 0 and 100 (inc.).
const loudness = require('loudness')
loudness.setVolume(45).then(() => {
// do something..
})
loudness.getVolume().then((val) => {
// val is current system volume.
// do something..
})
loudness.setMuted(false).then(() => undefined)
loudness.getMuted().then((muted) => {
// muted
})
Currently Mac OS X, Linux (ALSA) and Windows NT is supported
