If it's any help, I'm in the process of bisecting this between tags Ubuntu-3.19.0-16.16 and Ubuntu-3.19.0-18.18 in this repo git://kernel.ubuntu.com/ubuntu/ubuntu-vivid.git
I'll report back any findings. I have an i3 NUC (NUC5i3RYH) with the same issue. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1457369 Title: kernel 3.19.0-18 breaks HDMI audio for snd_hda_intel Status in linux package in Ubuntu: Triaged 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.
