Thanks for that. I've never seen pulseaudio do this before.

1. Do you have any ideas as to what apps might have been using
pulseaudio recently?

2. Is the problem regular? Does it return after a reboot?

3. Does the same problem exist in Ubuntu 19.04 if you boot that from
USB? (http://releases.ubuntu.com/19.04/) We use a newer version of
PulseAudio in all Ubuntu releases from 18.10 onward so I am wondering if
this is a bug that was fixed already.
