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 OBSERVED RESULT Volume still set to initial level. EXPECTED RESULT Volume level should be at the new level. SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.14.4 KDE Frameworks Version: 5.54.0 Qt Version: 5.11.13 ADDITIONAL INFORMATION Volume level at login is fixed at 40%. At one point it was fixed at 20% and somehow changed to 40% with no clear understanding why.
You need to enable module-device-restore and if you want also module-stream-restore Pulseaudio modules.
How is that accomplished? There are no user accessible options to enable any PA modules in KDE that I can find.
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.
