Before adding to blacklist, could you try some usual suspects?
For Lenovo, you can try at first to pass
  model=,tpt440
to snd-hda-intel module.

(the first comma is no typo but to pass the model name to the second
 controller for Realtek.)

The above will add some bogus dock jacks, so it's no solution but to
just to test whether it avoids the clicking noise.


thanks,
