Each amplifier within the LM4766 has an independent smooth transition fade-in/out mute that minimizes output pops. The IC’s extremely low noise floor at 2µV and its extremely low THD+N value of 0.06% at the rated power make the LM4766 optimum for high-end stereo TVs or mini-component systems.

The muting function of the LM4766 allows the user to mute the music going into the amplifier by drawing more than 0.5mA out of each mute pin on the device. UNDER-VOLTAGE PROTECTION Upon system power-up, the under-voltage protection circuitry allows the power supplies and their corresponding capacitors to come up close to their full values before turning on the LM4766 …

Muting Circuits For Audio
https://www.sound-au.com/articles/muting.html
Mute circuits are also used at the inputs of many professional power amps. In some cases the signal is muted if the amp gets too hot, and nearly all mute the inputs for 1 - 5 seconds after power on. This is done so that turn-on/ off noises from mixers and other gear is blocked in case the entire system is powered up at once.
Op. Amp. Preamplifier with mute - Audio forum - Audio - TI ...

The amplifier feedback will be controlled with a digital potentiometer, I want to implement also the mute feature, could I take advantage of the op. amp. shutdown? In shutdown mode the op. amp output will act as an open circuit, so the only way for the input signal from the input to the output is the feedback net, correct?
