PA/PW use only ALSA controls at the moment - thus you should define
JackControl as defined in use-case.h. But it seems that the driver

"iface=CARD,name='HDMI/DP,pcm=2 Jack'" jack controls for HDMI).

Ah, thank you Jaroslav. That's the hint I was searching for atm.
JackDev vs. JackControl. I had a vague guess on this but now you made it
certain.
Maybe I should take a look into the driver directly.
It seems that many ASoC drivers do not create kctls - the argument pins
is zero in the snd_soc_card_jack_new() call. The SND_JACK_HEADSET should
be remapped to kctl in sound/soc/intel/boards/sof_rt5682.c, too.
Did you mean something like the patch below Jaroslav? If yes, most of
the Chromebook machine drivers are missing this remapping. That would
also explain why the jack detection didn't work on my GLK test device,
despite a UCM file that looked good...
Yes, it looks like a way to go. It seems that the drivers were tested only
with the CRAS audio server. Note that pulseaudio can be run with the user
permissions only - thus the input devices may not be reachable.
Thanks,
Jaroslav
