After upgrading from 3.16.0-38-generic (Ubuntu Utopic) to 3.19.0-18-generic (Ubuntu Vivid) my audio stopped working. The issue appears to be in the snd-hda-intel driver.

HDMI fail because drm/i915 fail

So it appears. I hadn't noticed these: | [000d00h02m01s] Could not create debugfs 'i915_pipe_update_start'

directory

| [000d00h02m01s] snd_hda_intel 0000:00:03.0: Cannot turn on display

power on i915

This patch add the error messge " Cannot turn on display power on i915"
