Play m4p with AudioQueue

Is it possible to play prote开发者_如何学Ccted m4p files with AudioQueue? I tried NSSound (it can play m4p) and the AudioQueue sample afplay (does not work otb). Is there any way to play m4p with AudioQueue?

What I discovered so far:

AudioQueue: no m4p support, because quicktime is responsible for the encryption.

NSSound: supports m4p (I assume that it is using quicktime to do it) but it definitely sucks at large sound files. (playback quality problems and performance problems)

QTKit: Can play m4p but only if you are not starting from Xcode or the gdb. It looks like this is a protection mechanism.

2014: NSSound does not support M4P. AIFF, WAV and NeXT SND file formats only.
