STEPS TO REPRODUCE 1. right-click on sound icon in system tray and click on "Configure audio volume..." 2. click on "Audio" in the left side 3. click on "Configure..." button on bottom OBSERVED RESULT nothing happens. "Configure..." button works when I open Audio KCM in System Settings. EXPECTED RESULT "Configure..." button should work SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.20.80 KDE Frameworks Version: 5.77.0 Qt Version: 5.15.1
Yes this is a known issue with multi-page KCM system when embedded into a Plasma configuration dialog. Raising to VHI since this is technically a regression with the new Audio KCM and we can't ship this way in 5.21. We'll get it fixed before the final release one way or another.

Git commit 839223aa261207260da46d5727190896985c8061 by Nicolas Fella. Committed on 19/01/2021 at 18:27. Pushed by nicolasfella into branch 'master'. Temporarily move KCM out of applet config The applet config window cannot handle multi-page KCMs so it's impossible to open the Advanced page when opening the KCM from the applet config. The notifications applet has this problem too. Apply the same workaround here. This is of course not a good solution, but adding proper support into the applet config is not going to happen before Plasma 5.21. This is better than having a broken KCM.
