["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Maarten Fonville, could you please test the latest upstream kernel
available from the very top line at the top of the page (the release
names are irrelevant for testing, and please do not test the daily
folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will
allow additional upstream developers to examine the issue.

If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where XY and Z are numbers corresponding to the kernel version.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.

Thank you for your understanding.

Title:
  kernel 3.19.0-18 breaks HDMI audio for snd_hda_intel

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Problem appears on multiple computers with exact same kernel update, so clearly the problem is within the kernel. 3.19.0-16 did work without any problems.
  Before sound worked great via HDMI, now the HDMI output is not visible in neither alsamixer nor pulseaudio. Audio via the headphone jack still works.
  The computers are Intel-NUC-Kit-D54250WYK:
