After installing qt 6.4.1 from the online installer, I compiled old code, and the message boxes were not playing any sound.
I saw that QMessageBox plays its sound via QAccessibleEvent so I tried this
QAccessibleEvent event(this, QAccessible::Alert);
QAccessible::updateAccessibility(&event);
But no sound is played!
I tried QSoundEffect and didn't work at first but it turned to be a bug in qt 6.4.1 and renaming "mfplat.dll" to "mfplat.dll.dll" next to the application solved it but the message box and accessibility sound are not played yet.
Is this a problem or qt removed playing alert sound with accessibility?
