Some debug shows that the dbus reply received in SystemTray::serviceNameFetchFinished() does not contain "org.pulseaudio.Server", so we never call newTask("org.kde.plasma.volume") and the applet does not show up in the system tray. Everything works fine in X11. Workaround: manually add the applet elsewhere.
So this is on Wayland? https://cgit.kde.org/plasma-pa.git/commit/?id=50157cc0de87d391998938a3ab817836fa05d496 This commit should probably be reverted, as it is actually possible to build PulseAudio without dbus support in which case the applet will never show up.
Yes, happens only in the wayland session.
My plamsa pa applet only starts in the system tray on every other login and I'm not using wayland. Login in and it is there Login again and it is gone Login again and damn it is back again!
Git commit e32c8904683d4ccf6362d30236425fb3d2b54438 by David Rosca. Committed on 13/06/2017 at 06:19. Pushed by drosca into branch 'Plasma/5.10'. Revert "Make the applet DBus activated" Pulseaudio may be built without DBus support, in which case it will never show up in tray. Also, this seems to make the applet never show up under Wayland. This reverts commit 50157cc0de87d391998938a3ab817836fa05d496.
