Is there a way to disable pulseaudio on a headless server?

My server is generting errors like ...

messages:4985:27:Feb 12 09:12:37 localhost pulseaudio[12243]: [pulseaudio] bluez5-util.c: GetManagedObjects() failed: org.freedesktop.DBus.Error.ServiceUnknown: The name org.bluez was not provided by any .service files

Config attached. TIA - George
