Two days ago the `wireplumber` package was made to replace
`pipewire-media-session` as the latter session manager for PipeWire is
considered dead upstream and will see no more releases. Unfortunately, this
step was premature.
Our pipewire audio packages (`pipewire-alsa`, `pipewire-jack` and
`pipewire-pulse`) ship configuration that prompt media-session to activate
PipeWire's audio features. When these packages are not installed and the
configuration is missing, PipeWire can be used for screen recording without
interfering with ALSA or PulseAudio.
WirePlumber disregards this mechanism and always configures PipeWire to grab
audio devices, meaning users of PulseAudio or bare ALSA experience broken audio.
The replacement has been reverted while we attempt to look for a better
solution switching to WirePlumber. If you are currently not using PipeWire for
audio and `wireplumber` got installed on your system, please reinstall
`pipewire-media-session` and reboot to restore audio functionality.
pacman -Syu pipewire-media-session
