I have had this issue through a few versions of firmware. I have nothing routed to the wedge but, as long as it is unmuted a slap back type echo happens to my stereo Aux 2 mix which just happens to be my drum monitor mix :S. I have been through all of the routing and I can’t see anything that would cause this but, it might be something I haven’t considered so I thought I would ask to see if someone has any ideas of how this is happening before I bother support.
