Hi all!
The current linux kernel (3.17 as well as 3.18-rc7) does not support
the audio output on a Lenovo Ultra Dock in conjunction with the X240.
The issue is discussed in [1], which provides a patch as well.
The patch is available at [2]. I'm asking you for integrating it into
your linux tree.
So it might be merged into the mainline kernel during the current or
the next development phase.
Thanks in advance!
Regards,
Alex
