Some of the amplifier / amplifier-chips, which can be used with squeezelite-ESP32 have a pin for mute / activation. It would be nice to be able to use this input to automatically switching the amplifier on / off when Squeezelite is playing or being activated. This could save some power and may reduce noise output on cheap solutions, when no output by squeezelite is produced.
Configure a GPIO pin (defining pin and also if high / low should be active).
There is already something similar for the raspberrypi version of squeezelite to control a relay:
" -G <Rpi GPIO#>:<H/L>\tSpecify the BCM GPIO# to use for Amp Power Relay and if the output should be Active High or Low\n"
Maybe this solution could be doubled and fitted to the ESP32.
