In this version of ubuntu, pulseaudio is a service started for the user. The different commands tried
> pulseaudio -k
> systemctl --user stop pulseaudio
> changing pulse.conf to include autospawn=no
> systemctl daemon-reload
> systemctl --user stop pulseaudio
> pkill -9 pulseaudio
It respawns all the time because systemd restarts it. Should i kill the systemd --user instance or is there something else that is tweakable?
