PulseAudio/Examples - ArchWiki
https://wiki.archlinux.org/title/PulseAudio/Examples
Correct interaction with PulseAudio is done using a D-Bus based audio card "acquire/release" mechanism. When JACK server starts, it asks this D-Bus service to acquire the audio card and PulseAudio will unconditionally release it. When JACK server stops, it releases the audio card that can be grabbed again by PulseAudio.

pulseaudio - Is it possible to set an order of preferred ...
https://unix.stackexchange.com/questions/685071/is-it-possible-to-set-an-order-of-preferred-loudspeakers-that-dynamically-change
I would like to set a priority of the devices like this: AVR; Portable soundspeaker; Monitor; Laptop; so that they would be magically autoselected when I change the configuratino (whcih can happen several times a day) Right now, PulseAudio tries to pick the best one and sometimes it suceeds, sometimes not.

https://unix.stackexchange.com/questions/258161/what-makes-it-possible-for-a-pulseaudio-process-to-get-the-nice-level-of-11
PulseAudio requires higher priority than other desktop programs mainly to avoid latency problems and get a skip-free audio playback. But the process that allows PulseAudio to have a higher priority is rather complex. To get this special priority, it uses the RealtimeKit (rtkit-daemon) process. This D-Bus service allows some user programs to use real-time scheduling and …
