No more HDMI audio output visible/working snd_hda_intel Cannot turn on display power on i915

[David Sommen]

All of a sudden, I believe as a result of a kernel upgrade, I cannot play sound via my HDMI output (television). The option is not listed anymore in sound settings or VLC. Video output on hdmi works fine. The internal speakers work fine as well.

I have lenovo ideapad u330p.

I can confirm it does work on the previous kernel, 3.19.0-16-generic. It does not work on 3.19.0-18-generic.

Similar symptoms here; audio over HDMI worked fine until update yesterday.
