I have an application for Google Chrome and I want it to issue a sound every time a notification is created, but in my tests I did not have much success = p
I do not know if it's some permission or if there really is not any way I can do it.
Do you know any way? (Detail: I wanted the js file in the background to do this)
Have you tried using the Web Audio API?
var context = new webkitAudioContext();
var oscillator = context.createOscillator();
oscillator.connect(context.destination);
oscillator.frequency.value = 780; //frequencia do som, altere pra mudar o som que será emitido
oscillator.start(0);
oscillator.stop(context.currentTime + 0.5)//duração do som;
If you use the light API in mind that the oscillator is destroyed after use, for each sound you must create a new one.
