android cannot get sound to play from a notification

I have the following code to produce a notification. The notification comes up but no sound. I have the following code to pouyt the sound on

notification.defaults |= Notification.DEFAULT_SOUND;

code listing

    NotificationManager manager = (NotificationManager)     gContext.getSystemService(Context.NOTIFICATION_SERVICE);

    Notification notification = new Notification(R.drawable.icon, "Teeth Alert", System.currentTimeMillis());
    PendingIntent contentIntent = PendingIntent.getActivity(gContext, 0, new Intent(gContext, NotifyMessage.class), 0);
    notification.setL开发者_高级运维atestEventInfo(gContext, "Your teeth appoitmernt:", "Date:", contentIntent);

    notification.defaults |= Notification.DEFAULT_SOUND;
    notification.defaults |= Notification.DEFAULT_LIGHTS;

    manager.notify(1,notification);
    cDates.SetAlarm(i);

You should try setting

notification.defaults = Notification.DEFAULT_SOUND | Notification.DEFAULT_LIGHTS;

or setting explicitly:

notification.sound = 
    RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

Not sure if you resolved this but I had the same problem and it's because you have

notification.defaults |= Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_LIGHTS;

but you need to assign it first like

notification.defaults = Notification.DEFAULT_SOUND;
notification.defaults |= Notification.DEFAULT_LIGHTS;

or more simply as @rekaszeru put

notification.defaults = Notification.DEFAULT_SOUND | Notification.DEFAULT_LIGHTS;
