pulseaudio 8.0-0ubuntu3.9 update broke sound on certain hardware, the dummy output profile is selected by default

[Open Sense Solutions]

I help manage a few hundred computers and since the last pulseaudio update a few weeks ago ( xenial-updates ) from pulseaudio_1%3a8.0-0ubuntu3.8_amd64.deb to pulseaudio_1%3a8.0-0ubuntu3.9_amd64.deb ( and libpulse0 ) certain hardware including dell models 755, 390, and 3050 lost sound. They were working fine for years but now the dummy output profile is selected by default. What happened?

This can be worked around by explicitly setting:
set-card-profile 0 output:analog-stereo
set-sink-port 1 analog-output-headphones

or by reverting back to pulseaudio_1%3a8.0-0ubuntu3.8_amd64.deb ( along with libpulse0 ) .

When I try to use apport it gets to the end and says "apport cannot connect to crash database" but I have included example system details in the attachment after the output of pacmd list sinks and default.pa. ( You can only attach one file ?!?)

I see now there is an option for additional attachments (one per comment) so I'm going to attache the files separately, here is the output of pacmd list sinks

here is the default.pa

here is the text from running:
apport-cli -f -p pulseaudio --save bug.apport
