Things were feeling a bit sluggish so I dropped to the desktop and did top in a terminal and saw pulseaudio was using 15%-18% CPU constantly and had already racked up 30 hours of CPU time. I checked doing a fresh install before doing apt update/upgrade, after doing a update/upgrade, and even doing rpi-update to get the latest kernel/firmware and in all circumstances it was using lots of CPU. I also checked with OpenAuto left open or closed and was the same in both cases.
