Cannot loop audio infinitely with QMediaPlayer using a `qrc:` QUrl

On Ubuntu 22.04, I have exactly the same problem as the one described in QTBUG-102360. I use Qt 6.4.2 installed via [aqtinstall|https://github.com/miurahr/aqtinstall].

I tried to run the example proposed by André De La Rocha (see attached archive) and the song does not loop on my system. More precisely, it plays only twice and stops playing after the second play.
