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

Jairo, Could you check if you reproduce this bug and if the patch fixes the problem? Thanks
So that we're clear - Vinod, you're seeing HDMI display in initialize properly, you're just not getting audio as well, correct?

Yes, with attached patch I see display codec up and responding but we never get HDMI plug in/out notifcation from gfx driver and playing audio is all silent and no errors
So I tried to reproduce this on KBL using v4.4-rc8 kernel, I am able to hear audio using headphones or through the Monitor speakers. However looks like this is not the problem, which kind of event notification are you referring to? I tried in other platforms but also can't see or hear an event when HDMI Hotplug. Would really appreciate if you can provide the steps you did to reproduce this, and what is the expected output.
Hi Vinod, Do you still reproduce it?
