QMediaPlayer Sound not working in other PCs

[digimonkey]

Hello,

I have a problem with QMediaPlayer play sound in a different PC than in the developed one.
The release program works just fine in the PC that I have developed (I've copied all *.dll,...), but trying to use the same program in a different PC there is no sound.
I have my sounds in my Resources and their are together with the images that I use, so it isn't path fail.

I create in the header (*.h) file my QMediaPlayer variable:

QMediaPlayer * ErrorSound;


At cpp, in the constructer, I load the sounds:

ErrorSound = new QMediaPlayer();
ErrorSound->setMedia(QUrl("qrc:/Error.wav"));

Further in the correct place I call it to play:

ErrorSound->play();


I've checked the Data.qrc (my resource file) and all files are there:
<RCC>
<qresource prefix="/">
.......other files
<file>Error.wav</file>
</qresource>
</RCC>

All image files and sound files are in same place, same folder, as the *.exe file.

If anyone got this problem and know how to fix it i would thank you for helping me out.

## UPDATE ##

I've tried a new thing, that is load the current path and load directly the sound, instead using it as resource.


mFilename = mDir.absolutePath();
ErrorSound->setMedia(QUrl(mFilename + QLatin1Char('/') + "Error.wav"));
ErrorSound->play();

The sound stills work in the compiled PC and not in others. What's the secret?

Have you distributed the necessary plugins with your application and are they installed where Qt looks for them?

http://qt-project.org/doc/qt-4.8/deployment-plugins.html or
https://doc-snapshots.qt.io/qt5-5.4/windows-deployment.html#qt-plugins

depending on your Qt version.

Edit: I don't develop on Windows, but the windeployqt tool looks like it might help ensure you have packaged all of the required plugins with your application. I develop on Mac and the macdeployqt tool is invaluable.

Hope that helps.
