This is very true, but the internet is full of mismatched information (see references), which is why in another post of mine I wrote…
It would also be nice to hear them (Manjaro Team).
Precisely to be able to know what was happening and to be able to help others too. 
So knowing what decision the Manjaro Team made - If this was the case - I would decide what I should do. Use “pulseaudio” or “pipewire”.
Thank you very much for all the information and clarifications! As soon as possible I will give you feedback.
I am an enthusiast of the Manjaro project (particularly with the KDE gui). So I try to be as participative as possible in the forums and try to make other people’s lives easier. I have also been helped a lot.
That is the spirit of free software! Thanks again!
