Hi, I recently bought a 2015 ThinkPad (X250) along with a dockstation (ThinkPad Ultra dock). The audio output (mini-jack) doesn't work on the dock station, but after some research it seems that the snd_hda_intel module just miss the correct pin configuration.
This pin configuration seems shared between 2014 and 2015 ThinkPads, so this patch just add the same quirk for the X250 subsystem product id. After that, the audio output works fine on the internal speakers, on the laptop output jack and on the dockstation output jack. I didn't add the CC: sta...@vger.kernel.org because I'm unsure how the ALSA maintainers stand on this, but similar previous patches have been targeted to stable so it might be worth adding it.
