Step 1 is incorrect
pipewire-pulse is a PipeWire package to replace PulseAudio
pamac info pipewire-pulse confirms that this package is marked as conflicting with pulseaudio
Description : Low-latency audio/video router and processor -
PulseAudio replacement
Conflicts With : pulseaudio pulseaudio-bluetooth
And pamac install pipewire-pulse requests removal of 2 packages from my system
To remove (2):
pulseaudio-jack 14.2-2 (Depends On: pulseaudio) extra
pulseaudio 14.2-2 (Conflicts With: pipewire-pulse) extra
Both packages pipewire-pulse and pulseaudio could not be installed because of the conflicts
It is good to see that pulseeffects v5.0.1 in Arch now has an accurate description because the misleading description in v5.0.0 created some confusion
Description : Audio Effects for Pulseaudio Applications
But the misleading package name is likely to continue to confuse some users
I would not recommend Manjaro users switch from PulseAudio to PipeWire because there appears to be no support available on this forum
But if users want to replace PipeWire with Pulseaudio, all that should be needed is to install the metapackage manjaro-pipewire
There is also a metapackage manjaro-pulse to get back to PulseAudio if needed
