In a terminal when opening a PyQt5 application that uses QMediaPlayer, the following error is displayed with audio unavailable: defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer".  When instructing pip to install pyqt5==5.9 (PyQt5-5.9-5.9.1-cp35.cp36.cp37-abi3-manylinux1_x86_64.whl), the error does not appear and audio works as intended. 

Most likely a Qt problem. Might possibly be a packaging problem (ie. a missing Qt plugin in the wheel).
