Playing sound on the N8 device

[jon21569]

I have been trying to get sound to work on the n8, and so far without success. I have tried QSound, Phonon, and SoundMixerController from the instructions from the link http://tamss60.tamoggemon.com/2010/04/22/proper-sound-and-background-music-with-qt-for-symbian/. I am doing this for a game so I would like to play multiple sounds at once so I would prefer the SoundMixerController.

Here is some of the code.
