There has been some delay for this (due to issues with Pipwire on Wayland), but all is ready now to make Pipewire the default sound option for KaOS.
To learn a bit more why this move:
https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/FAQ

There are a few options however how to implement this change:

  • Automate the switch, adjust packaging so all users automatically move to Pipewire on updating
  • Wait for the next ISO, set the Live environment & new installed system to use Pipewire, existing installs won't be touched
  • Make it optional with the next ISO. Add a module in Calamares where the user can choose between Pulseaudio & Pipewire (similar page as is now in use for bootloader options and selecting minimal install/office suite)

How to move to Pipewire?

Automated for all users
Default in next ISO
Optional in Calamares
This poll has ended.

If there is issue in Wayland you can wait to be resolved then automated to everyone?

    bvbfan As said, there were issues, all resolved, that is why ready now.

    And for all, here is the new page in Calamares that can be used (regardless of it being automated or only introduced in the next ISO, this page can be presented so users can opt out of Pipewire):

        I'm using Wayland + build repo, so i will test it when it comes.

            Wireplumber was the one that needed a small patch, so needed for you now:

            sudo systemctl --global enable pipewire.socket
sudo systemctl --global enable pipewire.service
sudo systemctl --global enable pipewire-pulse.socket
sudo systemctl --global enable pipewire-pulse.service
sudo systemctl --global enable wireplumber

            and reboot, check that Pipewire is running with pactl info

                When i run those commands and reboot, i see "no devices" in the audio panel. In journalctl i see some d-bus erros on both wireplumber and pipewire. I restore by running the same commands with disable

                    After updating today wireplumber 0.4.10-3 (and plasma to 5.25.2) everything works fine on X
