The circuit should mute sufficiently any audio from 15 hz to 20 khz. Mute level should *easily* reach -50db. If not, you don't have the circuit wired correctly. This circuit will also fade by providing a variable voltage at the junction of the 33k and 1M0 resistors (R3 and R4). The fade will be low in distortion until -20 db has been reached.

This stereo audio switch circuit allows that with only one switch to select one of the four stereo channels. The internal switching is made posible with CMOS components. Each switch input includes a voltage divider to allow the switch to work in the linear zone of the characteristics, this ensures low audio signal distorsions.

This would be fed via a Schmidtt trigger into an IO line. At a push the Schmidtt may be avoided if the logic levels are 3.3V. The hard way means that the signals levels are lower than 3 or 4 volts peak-to-peak and an input amplifier needs to be inserted to boost the signal up to these sort of levels. There are simpler audio detectors based ...

Line level is the standard signal strength at which most audio equipment is designed to operate. Lower-level microphone and instrument signals must be brought up to line level with a preamp before interfacing with most equipment. These line level signals are then further amplified to drive speakers and headphones for playback.
Line level - Wikipedia
https://en.wikipedia.org/wiki/Line_level
Line level is the specified strength of an audio signal used to transmit analog sound between audio components such as CD and DVD players, television sets, audio amplifiers, and mixing consoles.. Line level sits between other levels of audio signals. There are weaker signals such as those from microphones (microphone level or mic level) and instrument pickups (instrument …

Line level is adequate for sending signals between devices, but not strong enough to power a speaker.In order to power a speaker, the line level signal needs to be amplified again. This can be done with a power amplifier.
