Upgrade from 20.04 to 22.04 killed audio input and output

Question

So I upgraded my system from 20.04 to 22.04 using the official upgrade window but now my audio is all screwed up. My audio has been replaced with "Dummy Output" and it won't detect input at all. I can lower or increase the volume of this dummy output but there is no output from either my speakers or my earbuds. What can I do so I can hear and say things?

While searching around on AskUbuntu and trying solutions, I did find something sus:

guninvalid@guninvalid:~$ pulseaudio -k
guninvalid@guninvalid:~$ echo $?
0
guninvalid@guninvalid:~$ pulseaudio
E: [pulseaudio] pid.c: Daemon already running.
E: [pulseaudio] main.c: pa_pid_file_create() failed.
guninvalid@guninvalid:~$ sudo pulseaudio -k
[sudo] password for guninvalid: 
E: [pulseaudio] main.c: Failed to kill daemon: No such process

Seems pulseaudio won't kill itself for some reason. Is this related?
