Linux dock audio
When headphones are plugged into the docking station, the speakers are muted but no sound is played through the headphones. This is reportedly fixed in Linux kernel 3.16. With older kernels, such as 3.13 that is shipped with Ubuntu 14.04, a workaround is available. Details are here: https://bugzilla.redhat.com/show_bug.cgi?id=1101386#c10
The bug was reported for a T440s, but it probably applies to all Intel Haswell based ThinkPads. The magic values are slightly different for each model though.
