On Ubuntu 17.10, Pulseaudio don't start at boot, but when I start it manually a few times, it works !? I tried pulseaudio -vv : https://pastebin.com/nZRwGR7z
You might have to add it to systemd startup
systemctl --user enable pulseaudio && systemctl --user start pulseaudio
The flags can be configured (from the manual):
Depending on whether --system, --user, --runtime, or --global is specified, this enables the unit for the system, for the calling user only, for only this boot of the system, or for all future logins of all users, or only this boot.
I had the same problem pulseaudio daemon not starting with Kubuntu 17.10 on my Asus laptop. What I found is that module module-switch-on-connect.so failed to load using pulseadio -vv command as user.
Commented out module-switch-on-connect.so from /etc/pulse/default.pa and this fixed my problem.
### Use hot-plugged devices like Bluetooth or USB automatically (LP: #1702794) #.ifexists module-switch-on-connect.so #load-module module-switch-on-connect #.endif
In your pastebin file I do not see an error not able to load a module by the way.
