Audio driver which is compatible with Screenflow Screenrecording software is not labeled
The Audio driver "Telestream audio capture", which is compatible with audible playback on my display and also with virtual recording on Screenflow recording software is selectable within MuseScore but not labeled.
It is visible and selectable with MuseScore 3.
Further several other available audio drivers which MuseScore 3 lists, are not visible or selectable anymore within MuseScore4, see in comparison attached screenshot number 2.
This was confusing me and I did not have an idea to select it. Now I have selected it and so I can now make a screen video from my score including audio recording, using screenflow.
