[Boot2Qt] The app freezes while switching audio outputs after suspending the playback

MacOS 15.3.2

Qt Creator 16.0.0

Qt 6.9.0RC

Device: Raspberry Pi4 64 bit with Qt 6.9.0 

Steps to reproduce:

1. Make sure you have 2 audio output devices connected (I have headphones and HDMI monitor)
2. Open audio output example - https://doc.qt.io/qt-6/qtmultimedia-audiooutput-example.html
3. Click suspend playback button.
4. Change the output device.

Expected: The output device is changed and the audio continue to play using this device.

Actual: The app freezes for 30 seconds. After that, the audio is played. If I don't suspend the playback the outputs can be switched without any issues. 

Reproducibility:  100%

Note: Reproducible on Boo2Qt, not reproducible on desktop.
