I have Ubuntu 14.04.03 working on my new Lenovo P50. There is one issue. Audio will not play out of the audio jack on the back of the docking station.
lspci -nn | grep Audio shows:
00:1f.3 Audio device : Intel Corporation Device [8086:a170] (rev 31)
I've tried modifying in /etc/modprobe.d/alsa-base.conf and adding these different options:
options snd-hda-intel model=thinkpad
and then I tried
options snd-hda-intel model=lenovo-dock
None of them worked. Anyone have any suggestions?
