Thank you for reporting this bug to Ubuntu.
Ubuntu 15.04 (vivid) reached end-of-life on February 4, 2016.
See this document for currently supported Ubuntu releases:

We appreciate that this bug may be old and you might not be interested
in discussing it any more.
Garry,
Did you ever update the BIOS, and did it fix the problem? I'm using a
Dell XPS 13 and have this problem following a recent install of 14.04.

Thank you for the message. I'm using a desktop and even a double cold
boot didn't help.
Unfortunately, all suggestions have produced deep silence from my
computer's audio system.,

In my case a single cold reboot worked. Thanks for the hint. But

HDMI sound on Ubuntu 15.04.

Can confirm this bug. Sound via HDMI worked in 14.04 and 14.10 but not
in 15.04. Pavucontrol shows in the configuration tab a long list of HDMI
outputs claiming all are unplugged (compare attached screenshot).
Previous Xubuntus only showed a single HDMI output that worked.

Thank you for your response. I do not have an XPS and Ubuntu 15.4 dual
boots with Windoz XP professional. Incidentally, Windoz sound works as
it should.
I tried two cold boots into Ubuntu, but unfortunately that did not fix
the problem.
Tomorrow, I'll look into updating the BIOS.
Thank you
Status changed to 'Confirmed' because the bug affects multiple users.

I found the solution here: http://bartongeorge.net/2015/04/09/4th-gen-
dell-xps-13-developer-edition-available/ : If dual booting with Windows
8.1 and kernel 4.0 or earlier you will need to cold boot twice into the
OS for audio to work.
