Public bug reported:
This issue has been present and fixed two years ago and with Trusty Tahr
it re-appeared:
When logging in and my display is extended to two monitors, and also
when the screen blanks, I get 3-5 seconds of horrible noise via
DisplayPort audio out.
The noise is loud enough to damage ears and loudspeakers, if volume has
been set to a normal listening level.
