SMUTE: Soft Mute Control
0: Normal operation (default)

0: Independent (default)
1: Dependent
At DATTC bit = “1”, ATTL7-0 bits control both channel attenuation levels, while register values of
ATTL7-0 bits are not written to the ATTR7-0 bits. At DATTC bit = “0”, the ATTL7-0 bits control the left
channel level and the ATTR7-0 bits control the right channel level.
ATS: Digital attenuator transition time setting (Table 18)
0: 1061/fs (default)
1: 7424/fs
