Bam, right on the money.  Disabling that module and restarting
pulseaudio makes the problem go away.

Both attached.  During the verbose logging, I tried playing an audio
file both with headphones on and off, to try and cover the whole range
of potential possibilities.  Both logs were made prior to the test of
