<pre>I can reproduce on re-icl-u with the mini-DP port and a real screen:
1. Unplug everything, boot the machine, run `cat /proc/asound/eld*`: no ELD
present
2. Plug an external screen which supports audio
3. Run dmesg. Grep for "ELD". Notice the lines "[drm:drm_add_edid_modes] ELD
monitor <monitor name>" and "[drm:drm_add_edid_modes] ELD size 36, SAD count 1"
3. Run `cat /proc/asound/eld*`: still no monitor present
4. Play a sound with aplay
5. Run dmesg. A bunch of "[drm:i915_audio_component_get_eld [i915]] Not valid
for port <port>" messages appear.
5. Run `cat /proc/asound/eld*`: monitor appears
Are we supposed to start playing audio to get the correct value in
/proc/asound/eld*?</pre>
