I cannot get any audio through the 3.5mm audio jack on my ThinkPad OneLink Pro
dock connected to my ThinkPad Yoga S1. The port work fine with Windows. I have
had this problem with all other Linux distros including OpenSUSE Leap 42.1, and
Fedora 23. If I am lucky I can get a bit of a buzzing sound when I set the
audio very loud but I usually don't even get that. This happends in both KDE
and GNOME so I'm pretty sure it's a kernel bug. I think it might be related to
https://lists.debian.org/debian-kernel/2015/11/msg00086.html.

I once managed to get the audio working by booting without the dock, plugging
it in and then configuring it with Yast because without the Yast configuration
it would not work. Using Yast after booting with the dock does not help though.
I can quite consistently get a buzz when testing the audio with Yast. Going
through all that isn't practical though and the fact that plugging and
unplugging the dock makes KDE go crazy doesn't help either...

I guess this must be some situation where the kernel isn't detecting the right
driver to load for the dock in the early boot process even though it can detect
the right one if asked to do so on a fully running system.
