Comment 20 for bug 1534776

I been doing some investigation since this doesn't still work, there's 3 things that i found need fixing:
  * qtmultimedia needs to install the usr/include/*/qt5/QtMultimedia/QAudioRoleControl and usr/include/*/qt5/QtMultimedia/qaudiorolecontrol.h files
  * qtubuntu-media needs to return an QAudioRoleControl on AalMediaPlayerService::requestControl with QAudioRoleControl_iid
 * AalMediaPlayerService::setAudioRole and AalMediaPlayerService::audioRole need to properly map between media::Player::AudioStreamRole and QAudio::Role since now they're only casting directly from one to the other and http://paste.ubuntu.com/15266060/ means that is not possible.

Jim will you take care of this?
