[Development] Audio playback depends on... Qt5Widgets.dll?

[Sze Howe Koh]

Hello,

I just found out that my Qt Quick 2 application can't use the Audio
element unless I deploy Qt5Widgets.dll along with it. Otherwise, I get
this at runtime:

    defaultServiceProvider::requestService(): no service found for -
"org.qt-project.qt.mediaplayer"


I then wrote a console application that does nothing except play a
.wav file through QMediaPlayer. Same result -- the sound plays if
Qt5Widgets.dll is present, but "no service found" otherwise.

Is this expected? I understand the dependency on the Qt GUI module --
QMediaPlayer handles videos -- but what's required from the Qt Widgets
module for multimedia playback?

More importantly, is it possible to remove this dependency?


Regards,
