Public bug reported:

Ubuntu 19.04 QA-Test (LIVE x86_64)

Dell optiplex d755, (c2d-e8300, 8gb, Tadeon HD 2400 PRO/XT)
Two dell displays, left is landscape, right is portrait

This live test had two packages added:  `vim` & `ubuntu-restricted-
extras`

Background: 
I added ubuntu-restricted-extras so I could run requested test on this system 
which had me streaming videos from utube - it was required to get around H264 
errors  (vim because I can't cope with other editors & added `multiverse` to my 
sources.

Issue:
With firefox streaming ABC News 24 (local AU news) I suspended machine.  Waited
Awoke machine - everything resumed as expected .. Some circling was apparent on 
firefox before picture resumed, however no sound.

I was unable to fix it using any tools installed - to fix I `sudo apt
install pavucontrol`, went to Configuration (or last tab) and
Profile=Off on the drop-down menu, then returned to Profile=AnalogStereo
Duplex.   This is something I do on occasion for this machine on
installed system or other machines I use.

This is really a minor issue, & may not be an issue on an installed
system (though I come across it semi-regularly & just live with it). In
regular use I pause/stop sound & know this makes this almost a non-issue
(almost never happens when sound isn't playing).
