Left/Right Playback Volume. VOLL and VOLR control the playback volume for both the DAC and line input
audio signals.
Note: Gain settings apply when the headphone amplifier is configured in differential mode. In the single-
ended and capacitorless modes, the actual gain is 5dB lower. Assuming LOGL/LOGR = 0dB, line output
gain is 6dB lower.

Left/Right Line Output Mute. LOLM and LORM mute both the DAC and line input audio signals.
0 = Line output is unmuted.
1 = Line output is muted.
