Description of problem:
No sound on fedora 35 after upgrading from 33
Figured wireplumber service was "inactive (dead)", worked after:
 systemctl --user start wireplumber.service
Figured it out from 
 https://ask.fedoraproject.org/t/no-sound-after-upgrade-install-of-fedora-35-rawhide/16302
and
 https://fedoraproject.org/wiki/Changes/WirePlumber

Version-Release number of selected component (if applicable): See below

How reproducible: Issue remains after reboot. I upgraded only once.

Steps to Reproduce:
1. Upgrade from fedora 33 to 35 using dnf system-upgrade download / reboot
2. check sound icon

Actual results: No sound device

Expected results: Sound devices present

Additional info:

Probably not a supported use-case. And my fedora 33 might not have been up-to-date enough.
Still, writing this report mostly in case it helps someone.
