[alsa-devel] No sound from Headphone Jack over Lenovo Docking Station with T440p Laptop

[Nicolas Kalkhof]

   Hello, I have a Lenovo ThinkPad T440p laptop connected to an Ultra
   Docking Station. Sound works fine over Laptop Speakers and the 3,5mm
   Headphone Jack. However that is not the case when I connect the T440p
   to the Docking station Type 40A10065EU and use the Headphone Jack at
   the Dock. I've tried loading the alsa module with the "model=thinkpad"
   or "model=lenovo-dock"  without success. My Distro is Gentoo and the
   Kernel is 3.13-rc4.

   alsa.conf:
   # ALSA portion
   alias char-major-116 snd
   # OSS/Free portion
   alias char-major-14 soundcore
   ##
   ## IMPORTANT:
   ## You need to customise this section for your specific sound card(s)
   ## and then run `update-modules' command.
   ## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
