That’s right, as of today the Kinetic iso (pending, not yet current since the changes were just made) has been updated to run only pipewire and not pulseaudio. So @copong, you can look forward to this for kinetic.
For Jammy, you might notice that you have both pipewire and pulseaudio running. This is because pulseaudio is still being used for the audio but pipewire is being used for the video. (Pipewire is needed for screencasting and screensharing on Wayland.)
I hope that clears up our plans regarding pipewire/pulseaudio but let us know if you have more questions
