The Phonon KCM module was removed on July 21st 2019, see https://phabricator.kde.org/D22616. It is replaced by plasma-pa, which is a pulseaudio applet. Documentation at https://docs.kde.org/trunk5/en/kde-workspace/kcontrol/plasma-pa/index.html#plasmoid suggests that it supplies a control module that has devices in it. So I suspect that rebuilding KDE with pulseaudio enabled will result in the resurrection of the ability to select devices in KDE.
