I've installed the Ubuntu QML Toolkit Preview as per the instructions on http://developer.ubuntu.com/get-started/gomobile/ (with a minor fiddle to get it working on 12.04). I'm trying to write an app that plays a sound file. Aparrently you can do this using QtMultiMediakit in QtQuick 1, but not in QtQuick 2 as used by the toolkit.

Is it possible to write an app using the toolkit that plays sound?

Problem solved, the answer is to use QtMultimedia 5.0, which now provides the Audio element.

Here's a quick example of how to play an mp3 file using MediaPlayer component from QtMultimedia and the Ubuntu UI toolkit:

import QtQuick 2.0
import Ubuntu.Components 0.1
import QtMultimedia 5.0

MainView {
    width: units.gu(100)
    height: units.gu(75)

    Page {
        title: i18n.tr("Simple Player")

        MediaPlayer {
            id: player
            source: "foo.mp3"
            onStatusChanged: {
                if (status == MediaPlayer.EndOfMedia) {
                    button.pressed = false
                    button.text = i18n.tr("Play")
                }
            }
        }

        Button {
            anchors.centerIn: parent
            id: button
            text: i18n.tr("Play")
            pressed: false
            onClicked: {
                if (player.playbackState == 1){
                    player.stop()
                    pressed = false
                    text = i18n.tr("Play")
                }
                else{
                    pressed = true
                    text = i18n.tr("Stop")
                    player.play()
               }
            }
        }
    }
}

It looks like so:
