Qt Audio Engine not in Ubuntu SDK

I am using Ubuntu 14.04. I installed Ubuntu SDK with no problems using the instructions on Ubuntu website. I created a new QML project. I want to create an app that uses Qt Audio Engine. Here is my code where I am testing for the Audio Engine:

import QtQuick 2.0
import Ubuntu.Components 0.1
import QtAudioEngine 1.0
import "ui"
MainView {
// objectName for functional testing purposes (autopilot-qt5)
objectName: "mainView"
// Note! applicationName needs to match the "name" field of the click manifest
applicationName: "com.ubuntu.developer..AudioEngineTest"
/* This property enables the application to change orientation when the device is rotated. The default is false.
*/
//automaticOrientation: true
width: units.gu(100)
height: units.gu(75)
AudioEngine {
}
Tabs { id: tabs HelloTab { objectName: "helloTab" } WorldTab { objectName: "worldTab" }
}
}

When I try to run the program, I am given an error: module "QtAudioEngine" is not installed.

The Qt Audio Engine is in the current Ubuntu QML API. Why is it not in the SDK? Should I somehow install it myself or will it be added by the development team?

I used this modified version of your code (small changes to tabs) to test what was missing:

import QtQuick 2.0
import Ubuntu.Components 0.1
import QtAudioEngine 1.0
import "ui"
MainView { // objectName for functional testing purposes (autopilot-qt5) objectName: "mainView" // Note! applicationName needs to match the "name" field of the click manifest applicationName: "com.ubuntu.developer.AudioEngineTest" /* This property enables the application to change orientation when the device is rotated. The default is false. */ //automaticOrientation: true width: units.gu(100) height: units.gu(75) AudioEngine { } Tabs { id: tabs Tab { title: "helloTab" } Tab { title: "worldTab" } }
}

You basically need to install the following package for a Desktop target:

sudo apt-get install qtdeclarative5-qtaudioengine-plugin

For Ubuntu Touch:

sudo apt-get install qtdeclarative5-qtaudioengine-touch-plugin

Finally you can test it with qmlscene:

$ qmlscene ./audio.qml
Module 'QtAudioEngine' does not contain a module identifier directive - it cannot be protected from external registrations.
unity::action::ActionManager::ActionManager(QObject*): Could not determine application identifier. HUD will not work properly. Provide your application identifier in $APP_ID environment variable.
default openal device = OpenAL Soft
device list: OpenAL Soft
AudioEngine begin initialization
creating default category
init samples 0
init sounds 0
AudioEngine ready.
