Then this means that pulse cannot open your real audio hardware and has 
loaded a Null output instead. You need to work out why pulse could not 
open your hardware. Running pulseaudio -k and then pulseaudio -vvv will 
usually give the necessary debug info for you to work out what the cause is.

Dunno what that error is. I'm guessing it doesn't like connecting to 
your server. Perhaps the it's using the old pulse client library that is 
still hanging around on your system? Unlikely tho' if pavucontrol works.

Indeed but you clearly do not have alsa configured to route sound via 
pulseaudio plugin (which is generally recommended if you are using 
pulse) - probably due to removing all the pulse packages, but as I don't 
use Fedora I'm not sure how this works there.

To be honest, if you're not really overly confident fiddling with quite 
low level stuff in terms of distro, then compiling your own server from 
source was probably not the best idea! Using /usr as a prefix was 
definitely a bad idea! Personally I'd have recompiled the rawhide SRPM 
and installed that if I was going to fiddle in a "just use it" kinda 
way. The only reason I'd use source is if I plan to develop and code 
(well, this is perhaps not true in my case these days, but certainly for 
those who are not super familiar with source-installs, it helps keep 
their system cleaner if they avoid it).

Not really sure how best to advise you here. I guess try and work out 
why pulse is not opening your sound device, then route your alsa via 
pulse and hopefully everything will work again.
