[Impact]

The 1:8.0-0ubuntu3.9 introduced a new problem on the machines which do
not have internal speaker on them. With the 1:8.0-0ubuntu3.8, even there
is no internal speaker and nothing plugged in the audio jack, the
profile is still set available, then the active profile is analog-
stereo; while with the 1:8.0-0ubuntu3.9, the profile is set to
unavailable, and the active profile is off, after users plug sth in the
audio jack, the active profile will not switch automatically, need users
to switch manually, this change is unfriendly to users.

[Test Case]

On the machines without internal speaker, open sound-setting and check
if there is some output devices in the UI, and play sound from the UI.
Under 1:8.0-0ubuntu3.9 there is no output device, and can't play sound;
under 1:8.0-0ubuntu3.8 there is output device, and can play sound.

[Regression Potential]

This is a revert, after reverting, the content of pulseaudio is exactly
same as 1:8.0-0ubuntu3.8

[Other Info]

none


Since the update 1:8.0-0ubuntu3.8 to 1:8.0-0ubuntu3.9 , pulseaudio is not showing anymore my soundcard.

https://launchpad.net/ubuntu/+source/pulseaudio/1:8.0-0ubuntu3.9

The command "pacmd list-sinks" only shows a dummy output

When running on a fresh install of ubuntu 16.04, the sound is ok.
When updating the install with locking the following files to version 1:8.0-0ubuntu3 the sound keeps working:
libpulse0:amd64
libpulse-mainloop-glib0:amd64
libpulse-dev:amd64
pulseaudio-module-x11:amd64
pulseaudio-module-bluetooth:amd64
pulseaudio-utils:amd64

When updating to 1:8.0-0ubuntu3.9, I just get a "dummy output".

I tried running the following versions of Ubuntu (live usb), and get the same issue (no need to update to get the problem)
17.04
17.10
18.04

I attached the result of command "pactl list"
I have also generated logs during the boot but I don't know how to attach multiple files
