OUTPUT MIXER CONTROL
Each of the four output mixers has the same four inputs:
The input signals to the left and right mixers (feeding HPOUTL/R and LINEOUTL/R) are enabled
using the register fields described in Table 38. These mixers do not provide volume controls on the
inputs or outputs. However, input signals can be attenuated at source using the control fields
LIN_VOL, RIN_VOL, DACL_VOL and DACR_VOL.
