It corresponds to "Mic Boost" control.

It sounds like so although it's just a guess work.

Maybe. The 0x0f and 0x10 are really mysterious setting on AD1986A.

Then, we seems to need reset 0x0f and 0x10 at each channel setting.
Try the patch below. This will reset 0x0f and 0x10 to 0 when 6ch
channel mode is chosen. On 2ch channel mode, these values should be
back to make mic and line working (and no surround outputs, of
course).
