Master Volume Down. Modifies output level on pins L_OUT and R_OUT .
Contains a 10 k
internal pull-up resistor. When asserted LO, decreases Master
Volume by 1.5 dB/sec. Must be asserted at least 25 ms to be recognized. When
asserted simultaneously with VOL_UP, output is muted. Output level modifica-
