What are ways to play a sound in PhantomJS/CasperJS? - phantomjs

Question

I've been searching the web for more than 3 hours now looking for relevant ways to play an audio file but unfortunately I can't find anything useful. I have a CasperJS that's automating some tasks and I wanted it to play an audio file (e.g. beep.wav) after it completes all the tasks. I wonder if it's possible.
casper.run(function(casper) {
fs.write( saveDir, JSON.stringify(content, null, ' '), 'w');
// play an audio file before exiting....
casper.exit();
});

You need to use Child Process Module to run your script, to play the music.
I created pl.sh script to play the music:
#!/bin/bash
mplayer "/music/downloads2/Technoboy - Into Deep.oga"
exit 0
Then I created CasperJS script:
var casper = require('casper').create();
casper
.start('http://domu-test-2/node/12', function(){
var childProcess;
try {
childProcess = require("child_process")
} catch(e){
console.log(e, "(error)")
}
if (childProcess){
childProcess.execFile("/bin/bash", ["./pl.sh"], null, function(err, stdout, stderr){
console.log("execFileSTDOUT: "+stdout);
console.log("execFileSTDERR:",stderr);
});
console.log("Shell commands executed")
} else {
console.log("Unable to require child process (error)")
}
this.wait(10000)// need to wait to play the sound
})
.run();
And then PhantomJS script:
var page = require('webpage').create();
page.open('http://domu-test-2/node/12', function() {
var childProcess;
try {
childProcess = require("child_process")
} catch(e){
console.log(e, "(error)")
}
if (childProcess){
childProcess.execFile("/bin/bash", ["./pl.sh"], null, function(err, stdout, stderr){
console.log("execFileSTDOUT: "+stdout);
console.log("execFileSTDERR:",stderr);
});
console.log("Shell commands executed")
} else {
console.log("Unable to require child process (error)")
}
setTimeout(phantom.exit,10000)// need to wait to play the sound
});
