Tatsächlich ein sehr interessantes Thema, erstaunlich was pipewire ohne zusätzliche Software nur durch eine entsprechende Konfigurationsdatei leisten kann.
Ich war neugierig und habe eine RT-fähige 10-Band-EQ Konfiguration und eine RT-fähige 10-Band-EQ-virtual_5.1_sound Konfiguration erstellt.

Dateien nach ~/.config/pipewire/pipewire.conf.d/ kopieren, target.object ermitteln und eintragen, für RT den Benutzer zur Gruppe "pipewire" hinzufügen, für den 5.1 Virtual Surround benötigt ihr noch eine HeSuVi-Datei HRTF Database, diese im Pfad ablegen und in der config den Benutzernamen im Pfad anpassen, neu starten, in den Audio-Einstellungen entsprechendes Ausgabe-Gerät wählen.
Viel Spaß damit
