In the case of the ADAU1446, setting these registers does not
affect system operation in any way.

This single-bit register controls the behavior of ASRCs[7:4]
(Channels[15:8]) on a loss of lock. When Bit 0 is set to the
default (0), ASRCs[7:4] (Channels[15:8]) mute with a volume
ramp. When Bit 0 is set to 1, ASRCs[7:4] mute abruptly. In
addition, setting this bit to 1 ignores the ASRC mute bits
(Bits[3:0]) in Register 0xE141 (see the ASRC[7:4] Lock Status
and Mute Register (Address 0xE141) section), so a mute only
occurs on a loss of lock.
In the case of the ADAU1446, setting this register does not
affect system operation in any way.
