OVOLC: Output Digital Volume Control Mode Select
0: Independent

When OVOLC bit = “1”, OVL7-0 bits control both Lch and Rch volume level, while register values of
OVL7-0 bits are not written to OVR7-0 bits. When OVOLC bit = “0”, OVL7-0 bits control Lch level and
OVR7-0 bits control Rch level, respectively.

When IVOLC bit = “1”, IVL7-0 bits control both Lch and Rch volume level, while register values of IVL7-0
bits are not written to IVR7-0 bits. When IVOLC bit = “0”, IVL7-0 bits control Lch level and IVR7-0 bits
control Rch level, respectively.
