I have an input-sensing power on capability on my amplifier that I use for
my Slimp3, i.e. the amp is in "standby mode" until it senses audio input,
then powers up to do it's job.

Using analog output, can the Slimp3 (or Squeezebox) support this type of
amplifier, or is there always an output signal generated even if the
slimp/sb is powered off?

I've tried with my Slimp3 with no avail - maybe there's a setting or
firmware update? I have firmware 2.2 with Server 5.1+
