[AK4128A]
SMUTE4: SRC4 Soft Mute Control
0: Soft Mute Release (default)
1: Soft Mute
In serial control mode (SPB pin= “H”), the SMUTE pin setting is ignored. SRC4 reflects the SMUTE4
bit setting.

In serial control mode (SPB pin= “H”), the setting of DEM1-0 pins is ignored. The DEM[11:10] bits setting is
reflected to SRC1, the DEM[21:20] bits setting is reflected to SRC2, the DEM[31:30] bits setting is reflected to
SRC3, and the DEM[41:40] bits setting is reflected to SRC4.
