I'd be grateful if someone could help with this 218 crackle problem:

I'm using my 218 as a Sooloos endpoint in my study. Inputs are (1) Sooloos via ethernet and (2) audio input from a computer via a DAC. The 218 outputs to a pair of DSP 3200s via SpeakerLink. That all works well.

Sometimes I want to listen via headphones. So I am outputting from the 218 via coaxial digital to a Mojo headphone amp. However I need to mute the 3200s because otherwise the Mojo outputs a horrible crackle to the headphones.

When the 3200s are muted (via the Sooloos IP control iPad app) it works well and the sound is good. But the mute turns off - i.e. the speakers become unmuted - when the Sooloos music queue switches from one album to another.

Is there any way to have a permanent mute, like the headphone mode on the 818v3?
