The muting is done with a volume ramp and is click and pop free.
If desired, the mute ramp can be disabled for Stereo ASRC[7:4]
(see the Stereo ASRC[7:4] Mute Ramp Disable Register
(Address 0xE143) section).
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 Stereo ASRC[7:4]
(Channels[15:8]) on a loss of lock. When Bit 0 is set to the default
(0), Stereo ASRC[7:4] (Channels[15:8]) mute with a volume
ramp. When Bit 0 is set to 1, Stereo ASRC[7:4] mute abruptly.
In addition, setting this bit to 1 ignores the ASRC mute bits
(Bits[3:0]) in Register 0xE141 (see the Stereo ASRC[7:4] Lock
Status and Mute Register (Address 0xE141) section); therefore,
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.
