Squeezelite provides the -G option:
Code:
--------------------
-G <Rpi GPIO#>:<H/L> Specify the BCM GPIO# to use for Amp Power
Relay and if the output should be Active High or Low
--------------------
I've never used it, so I'm not sure what triggers the signal. It's
probably Squeezelite soft power, rather than the presence of an audio
signal.
