Hi,

What's your Qt version ?
On what OS ?

It was clearly not possible to do so in earlier Qt versions, see: https://bugreports.qt.io/browse/QTBUG-9253

I cannot tell you if that has changed, though.

From a quick look at the sources of QSound, it seems to still be the case, but it can be worked around using QTemporaryFile for example.

@SGaist
like this?

auto player = new QMediaPlayer(this);
player->setMedia(QUrl::fromLocalFile(QTemporaryFile(":/sounds/sound1").fileName()));
player->play();

doesn't work though

I guess you will have to create a temp file, copy the contents from the resource file to the temp file and then open the temp file.

You can get some inspiration from here: http://www.qtcentre.org/threads/18644-QSound-and-embedded-resources

but I would not take it directly as it does not seem to operate on a temp directory. and operating on the program directory is forbidden on most operating systems.

Hi again @user4592357

In case you are still interested, I just tried myself and a simple QSound::play(":/claves.wav"); did work for me.

There was no need to create temporary files.

I've created a documentation update: https://codereview.qt-project.org/224476 to explicitely state that playing from resources is possible nowadays.
