Dear all,
(please cc)
I am trying to get HDMI audio output via a Lenovo Dock Ultra in
combination with a Lenovo Thinkpad X260.
When plugging the HDMI device (screen) directly into the laptop,
audio output can be selected in pavucontrol / Configuration, but
when the laptop is connected via the dock all the HDMI devices
appear as unplugged.
I have googled a bit and found a similar case for T430:
http://permalink.gmane.org/gmane.linux.alsa.user/36896
and checking the source code of snd_hda_intel it seems that
options snd-hda-intel model=lenovo-dock
should help, but indeed it didn't.
I am running Debian/sid, on today's git kernel (4.9.0-rc5+).
I attach the output of alsa-info.
Please let me know whether I can try some more tweaks.
Thanks a lot
Norbert
