["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Daniel Saier, the next step is to fully reverse commit bisect from
kernel 4.2-rc4 to 4.2-rc5 in order to identify the last bad commit,
followed immediately by the first good one. Once this commit has been
identified, then it may be reviewed as a candidate for backporting into
your release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

Title:
  No sound on ThinkPad docking station

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  I have a Thinkpad T450s. The sound works normally unless it is plugged
  in to the docking station (a ThinkPad Ultra Dock). If speakers are
  plugged in to the dock, the internal speakers get disabled correctly,
  but the output of the docking station does not work. Speakers which
  are plugged in directly on the Laptop still work.
