OUTPUT SIGNAL PATHS ENABLE
The output mixers and drivers can be independently enabled and disabled as described in Table 48.
Note that the headphone outputs LOUT and ROUT have dedicated volume controls. As a result, the
output PGAs LOPGA and ROPGA do not need to be enabled to provide volume control for the LOUT
and ROUT outputs.
