Controls the output bias current for the lineout amplifiers. The
nominal recommended setting for a 10kohm load with 1nF
load cap is 0x3. There are only 5 valid settings.
0x0=0.18mA, 0x1=0.27mA, 0x3=0.36mA, 0x7=0.45mA,
0xF=0.54mA

Lineout Amplifier Analog Ground Voltage
Controls the analog ground voltage for the lineout amplifiers in
25mV steps. This should usually be set to VDDIO/2.
0x00 = 0.800V

0x1F = 1.575V

0x23 = 1.675
0x24-0x3F are invalid

Lineout Right Channel Volume
Controls the right channel lineout volume in 0.5dB steps.
Higher codes have more attenuation. See programming
information for Left channel.
Reserved
Lineout Left Channel Output Level
The LO_VOL_LEFT is used to normalize the output level of
the left line output to full scale based on the values used to set
LINE_OUT_CTRL -> LO_VAGCNTRL and CHIP_REF_CTRL
-> VAG_VAL. In general this field should be set to:
40*log((VAG_VAL)/(LO_VAGCNTRL)) + 15
Table 18 shows suggested values based on typical VDDIO
and VDDA voltages.
After setting to the nominal voltage, this field can be used to
adjust the output level in +/-.5dB increments by using values
higher or lower than the nominal setting.
