Audio cannot be played in the emulator

[XiaoGuo, Liu]

I have a sample application at:

bzr branch lp:~liu-xiao-guo/debiantrial/bubblekid

The application plays some background music using the following code:

        SoundEffect {
            id: bubblepop
            source: "sounds/bubblepop.wav"
            volume: 1.0
        }

        MediaPlayer {
            id: backgroundMusic
            source: "sounds/background.mp3"
            autoPlay: true
            loops: MediaPlayer.Infinite
            volume: 1.0
        }

The app works well on the phone and on the desktop environment without any problem. However, it cannot play the music in the emulator. A developer also found this problem, and she needs the feature to test the app since she does not have a phone yet.

I test it using the following image:

phablet@ubuntu-phablet:~$ system-image-cli -i
current build number: 206
device name: generic_x86
channel: ubuntu-touch/ubuntu-rtm/14.09-proposed
last update: 2015-03-12 01:35:11
version version: 206
version ubuntu: 20150312
version device: 20150116

Best regards,
XiaoGuo
