I have an HTML page with audio element that I open in Qt WebEngine. When the page and the audio file are loaded from disk ("file:///index.html"), everything is OK. When they are added to resources and loaded from there ("index.html" or "qrc:/index.html"), audio abruptly ends in a matter of seconds. Adding preload attribute to the audio element gives it a bit more time to play, but it doesn't finish nonetheless. The audio file is in OGG format, tried different files. Minimal reproducible example is attached.
