I'm not sure I understand the objection. Would you rather I 
mention its audio capabilities before screen sharing? Or would 
something like "PipeWire media processing" seem to suit it better 
for you?

Truth be told, I find succinctly describing PipeWire for this 
context to be pretty difficult. It does a lot, and it's all pretty 
abstract. PipeWire is just plumbing for services people actually 
care about, and I don't think "PipeWire make media worky" is going 
to fly 😉.

Thanks for the pointer. I'll try to dig through the documentation 
to see what I can do. I find the Linux sound ecosystem to be 
pretty confusing. For instance: I thought ALSA was the backend 
that PipeWire used on Linux already, so I don't understand how 
ALSA can also use PipeWire as a backend.

My use for this patch was Wayland-motivated, and everything 
outside of basic functionality (screen sharing and playing audio 
from Firefox and MPD) wasn't something I spent much time on — 
since I really don't know much about it — in the hopes that we 
could provide a minimum level of service for people and add better 
support as people needed it as time went on.
