pipewire

I have pipewire installed .... but not sure if it is being used by the system. Gslapt reports that pipewire depends on libavahi ... avahi x64 is installed, What am i missing here?

You're not missing anything. I wrote the dependency wrongly. It should be avahi (not libavahi), so you should be good to go. You may want to download qpwgraph too, and if you have pulseaudio application, then perhaps install pulseaudio as well.
Open three consoles, the run pipewire in one, wireplumber on another, and pipewire-pulse on the last one; and you should be set for life 
Remember from Fatdog's point of view, both pipewire and pulseaudio are experimental packages. If things don't work, please don't complain, instead suggest what could be done to make it work, thanks

recent wireplumber depends on libpipewire 1.0.2 or higher .... recompiling.

Don't build a standalone wireplumber, instead, get pipewire and build it from there.
wireplumber is a subproject of pipewire. They need to go hand in hand.

Got it! Thanks
EDIT: pipewire on linux on a chromebook!
