Description

Linux Ubuntu 22.04
Qt Creator 12.0.0
Device: Raspberry Pi4 64 bit

Steps to reproduce:

Make sure there are more than one audio output connected to RPi (I used HDMI monitor, headphones and USB sound card)
Open the widgets player example - https://doc.qt.io/qt-6/qtmultimedia-player-example.html
Run it on Raspberry Pi 4 64bit
Open video file with sound.
Start switching audio output.

Expected: The audio output selection is changed.

Actual: The app freezes and could not be used. Rebooting the device is the only option to recover.

Reproducibility: 100%

NOTE: It does not matter from which audio device I switch to. I tried switching from HDMI to built-in and from built-in to HDMI. In all the cases the app breaks.
