Description Kai Uwe Broulik 2025-10-22 15:48:07 UTC

SUMMARY
When using systemd user sessions (the default nowadays), the startup sound plays as soon as the plasma-workspace-(wayland).target unit is launched, which is pretty much as soon as ksplash appears.

With the old codepath it is correctly only played when startup has finished just before ksplash disappears.

STEPS TO REPRODUCE
1. Enable login sound
2. Log in

OBSERVED RESULT
Startup sound plays as soon as ksplash appears

EXPECTED RESULT
Startup sound plays just before ksplash disappears/desktop appears

startkde: Move startup sound into a dedicated plasma-startupsound service

The startup sound is only supposed to play once the session is up.
The legacy codepath played it at the end whereas the systemd one plays
it as soon as the workspace target is *started*.

Add a dedicated `plasma-startupsound` service that is executed once the
workspace target is reached to ensure the sound doesn't play prematurely.
