ADAU1761 ALC disable setup

For digital microphone (ADMP521) connection I disabled ADAU1761 ALC circuit under DSP registers.

  The reason is that during speech test I can hear clipping, when phrase is starting.

  But with disabled ALD I’m still observing signal clipping for 4mS after applying 1 KHz burst@94dbSPL.

  (See attached picture). 

  Any ideas?
