Description Fred Wells 2019-02-14 22:43:26 UTC 
SUMMARY
Audio Volume level settings not saved across logins.

STEPS TO REPRODUCE
1. Login to KDE
2. Adjust audio volume to new level
3. Logout & Login again

Volume still set to initial level.


EXPECTED RESULT

Volume level should be at the new level.

You need to enable module-device-restore and if you want also module-stream-restore Pulseaudio modules.
Comment 2 Fred Wells 2019-02-15 18:16:13 UTC 
How is that accomplished?  There are no user accessible options to enable any PA modules in KDE that I can find.
Comment 3 Fred Wells 2019-02-15 18:29:37 UTC 
So, I managed to find pacmd enable-module for this purpose.  Of course, this is not a general user solution even if it worked, which it doesn't. :(

These modules are now enabled, as indicated here...
$ pacmd list-modules  | grep restore
        name: <module-device-restore>
                module.description = "Automatically restore the volume/mute state of devices"
        name: <module-stream-restore>
                module.description = "Automatically restore the volume/mute/device state of streams"
        name: <module-card-restore>
                module.description = "Automatically restore profile of cards"
        name: <module-default-device-restore>
                module.description = "Automatically restore the default sink and source"

If you have those modules loaded then it should work.
plasma-pa is just volume control application, it doesn't handle anything else (including restoring old volume), that's PulseAudio's job.
