applicaion using pyqt4(packaging by pyinstaller) doesn't play sound

in pyinstaller, hook-PyQt4.phonon.py need to be modified as follow:

hiddenimports = ['sip', 'PyQt4.QtGui', 'PyQt4._qt']

from hooks.hookutils import qt4_phonon_plugins_dir


pdir = "/Developer/Applications/Qt/plugins"
datas = [("/Developer/Applications/Qt/plugins/phonon_backend/libphonon_qt7.dylib", "qt4_plugins/phonon_backend"),
]
