These patches hopefully fix jack detection (and ELD information querying too) for Intel HDMI LPE. I don't have the hardware myself, so further testing would be very welcome. Hans, Takashi and Pierre, you're in Cc, because you indicated in this[1] thread that you have the hardware. Testing instructions: First, before installing the modified PulseAudio version, check if you still suffer from the problem that the kernel kills PulseAudio. I don't know if these patches are sufficient to fix that problem, but it's worth trying. Next, apply the patches on top of the current PulseAudio master branch and install the modified version. After installing, set "realtime-scheduling = no" in daemon.conf to prevent the kernel from killing PulseAudio. Then, start pulseaudio and check if jack detection is working. "pactl list cards" will show the cards, their profiles and the port status. The HDMI card should only list HDMI profiles in the "Profiles:" section (check that there are no analog profiles listed), and the port status should change between "available" and "unavailable" in the "Ports:" section as you plug the HDMI cable in and out. If the jack detection seems to work, try setting "realtime-scheduling = yes" in daemon.conf to see if the kernel still kills PulseAudio.
