Sounds good ("Approved" :).  We're also interested in making use of OpenAL
in QtMultimedia* so it sounds like a good way to start.

I'd prefer QtOpenAL because there are other 3D audio systems (if less
popular), but there may be a trademark issue.  I've asked Cristy about
this and I'll send another email.  It is probably necessary to delay the
playground initiation until after that.

This part is also something we've been looking at doing in QtMultimedia
(e.g. QMediaPlayer -> raw PCM, or via other classes).  Currently we use
whatever platform media framework we have to decode audio which might
result in differences between platforms though.  It would be nice to share
some of that code someway or another.
