Currently we only use PA with LE Audio Broadcast, so there is no dedicated API for PA alone, broadcast is enabled via experimental flags, you can find more information in pipewire regarding the main.conf options for LE Audio: https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/LE-Audio-+-LC3-support If you need PA for something other than Broadcast let us know, we might need to extend our MGMT APIs to allow usage of that. -- Luiz Augusto von Dentz
