I am currently having the same problem, there is a setting (which I have not found again yet) to change into a mode to enable quiet startup, so you dont accidentally turn devices on when their volume is up loud, I believe this could be the cause but as I said I am still looking for that setting! Constantly have to keep changing speaker output in Simplink every switch on
