Digging into the pulse config on 18.10, it looks like instead of using
the daemon mode it's trying to setup up some sort of IPC socket, but
this isn't getting run correctly:
tessa@viper:~$ systemctl start pulseaudio.socket
tessa@viper:~$ systemctl status pulseaudio.socket
● pulseaudio.socket - Sound System
Loaded: loaded (/usr/lib/systemd/user/pulseaudio.socket; enabled; vendor
preset: enabled)
Active: inactive (dead)
Condition: start condition failed at Sun 2018-10-21 10:37:45 PDT; 4s ago
└─ ConditionUser=!root was not met
Listen: /run/pulse/native (Stream)
note that it requires a non-root user, but running as more normal user
for some reason evaluates to root and fails.

Title:
no sound after 18.10 upgrade
Status in pulseaudio package in Ubuntu:
New
Bug description:
After upgrading to 18.10, the sound in my System76 Oryx Pro no longer
works, it no longer shows any of the audio output devices, not even
the builtin HDMI which usually always shows.
Not sure what happened, but this is a major regression and needs to be
fixed. Note that this isn't the same as the bug with Timidity taking
exclusive soundcard access
(https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1797714) as
I don't have any timidity packages installed.
