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, Takashi
