Pushnotification play sound


I am creating an app with ionic and ngCordova. The app shell receive push notifications.

I have adopted an example from ngCordova.


My .run method looks like this:

.run(function ($ionicPlatform, $rootScope, User, $cordovaDialogs, $cordovaVibration, $cordovaPush) { $ionicPlatform.ready(function () {
             var androidConfig = {
                 "senderID": "xxx",

             $cordovaPush.register(androidConfig).then(function(result) {
                 // Success
             }, function(err) {
                 // Error

             $rootScope.$on('$cordovaPush:notificationReceived', function(event, notification) {
                 switch(notification.event) {
                     case 'registered':
                         if (notification.regid.length > 0 ) {
                             console.debug('registration ID');

                     case 'message':
                         // this is the actual push notification. its format depends on the data model from the push server
                         alert('message = ' + notification.message + ' msgCount = ' + notification.msgcnt);

                     case 'error':
                         alert('GCM error = ' + notification.msg);

                         alert('An unknown GCM event has occurred');

I send push notifications with the following script:

The messages arrive, as far so good.

But I can’t manage to play a sound/tone. According to GCM documentation, this should work with the parameter sound and the value default.

My GCM request looks like this:

$apiKey = "YOUR GOOGLE API SERVER KEY"; $devices = array('YOUR REGISTERED DEVICE ID'); $message = "The message to send";

$gcpm = new GCMPushMessage($apiKey);
$response = $gcpm->send($message, array(‘title’ => ‘Test title’, ‘sound’ => ‘default’));

Has someone an idea why the sound is not played?

Thank you in advance!

Has Anybody a idea, i can not solve this problem
