Again, sorry for the delayed response on this - I only just discovered you've created a topic.
Is this actually feedback - ie are you too near Suzy when streaming audio through your phone and getting a feedback loop?
Or are you experiencing a clicking sound when listening in remotely? This sounds like it could be interference on the electronics/hardware. If this is the case please create a ticket and we will pick up the case.
This sounds like it could be electrical interference on your particular Suzy. How bad is it? Would you like to create a ticket so we can look into solutions?
