161 	   4 are used to identify and configure the board. With the advent of PnP,
162 	   these first 4 addresses have become obsolete, and software applications
163 	   only use the last 4 addresses to control the codec chip. Therefore, the
164 	   base address setting "skips past" the 4 unused addresses.
