            Bug ID: 93638
           Summary: [KBL HDMI] No audio and jack detect broken
           Product: DRI
           Version: XOrg git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: vinod.koul at intel.com
        QA Contact: intel-gfx-bugs at lists.freedesktop.org

For KBL HDMI we tried testing on v4.4-rc8 + drm-intel-nightly (5th Jan), we
fail to see jack detect event notification from display side. (snd-hda use i915
component interface for jack notification as well as UR from codec).

ELD read was also failing. Thereby no playback was heard when we tried
playback.

Attached is the patch for adding HDMI device in snd-intel (patch-hdmi) which we
are trying to verify on KBL
