it would be great to have a UI access to add EQ settings to audio devices. Currently it is possible by adding a config to pipewire.conf.d. But it would be nice if that could easily be set per device and replace the device in the volume control gui.
Simply install the famous EasyEffects, it recentely migrated from GTK LibAdwaita to Qt, you will have a wide range of options and excellent audio effects, and it can autostart and run as background session without consuming too much RAM or CPU.
