Description of problem: Install Mageia 7 - Netinstall with LXQt Desktop. Select LXQt with OpenBox. Add the "Volume control/Volume" to the (right) taskbar. If you click on "mixer" in the volume manager in the taskbar icon nothing happens. This is because it uses as default setting "pavucontrol-qt" but Mageia only installs "pavucontrol", so it can not start the volume mixer settings, because of missing -qt variant. A solution is to manual install "pavucontrol-qt" or to change the setting to "pavucontrol" (which looks not so good). The best solution would be, if Mageia installs pavucontrol-qt as default (depency).
