I have switched to the flatpak version as @del00m proposed and indeed it starts correctly. That version of PulseEffects is 4.8.5 while the repository's is 4.8.4.
Changelog for 4.8.5 just says "Improved compatibility with dconf 0.40. Now our plugins should be enabled when using this version.", so maybe the solution is to update the PulseEffects package in the repository to 4.8.5+ :) -- You received this bug notification because you are a member of DX Packages, which is subscribed to d-conf in Ubuntu. Matching subscriptions: dx-packages https://bugs.launchpad.net/bugs/1948882 Title: PulseEffects does not properly initialize on startup Status in d-conf package in Ubuntu: Confirmed Status in pulseeffects package in Ubuntu: Confirmed Bug description: In KUbuntu 21.10, PulseEffects no longer initializes its effects chain on startup. I usually use only Equalizer, so when I log into KDE, this equalizer does not get activated. To ativate it I need (i) start PulseEffects GUI, (ii) untic and tic again the "Equalizer" box. This is rarher annoying sequence that I have to repeat each time I login. Previousy, in ubuntu 21.04, all this was unnecessary. PluseEffets just worked immediately after logging in, without any additional actions. I would expect the same behaviour in 21.10.
