@Anthony-Abboud for the crackling sound issue, I could fix my issues with https://codereview.qt-project.org/c/qt/qtmultimedia/+/503818 and this is such a generic error that I expect that you hit the same problem. For the missing sound output, the following changed helped me https://codereview.qt-project.org/c/qt/qtmultimedia/+/503819 . Yet for that I am not sure yet if it is a proper solution or just a workaround.

@SGaist and @Kent-Dorfman Thanks for your inputs.

@RedMarsBlueMoon How do you iterate through the available devices? Could you give a code snippet? We use QtQuick and use the Audio component to play audio. So nowhere in the code do we get a list of audio devices or iterate through them.
