[PyQt] PyQt5 5.10 regression defaultServiceProvider::requestService(): ...

[Mandeep]

Hi all,

On Debian based systems (possibly other distributions as well), there seems to be a regression in PyQt5 version 5.10 installed via pip in a virtualenv (specifically PyQt5-5.10.1-5.10.1-cp35.cp36.cp37.cp38-abi3-manylinux1_x86_64.whl). 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. 

Please let me know if more information is needed.
