I started having the same issue. When I open the App on my Samsung Galaxy S9+ phone and select "Tap to go Live" it starts the crackling noise. I changed the unit twice and tried using data on my phone as a hot spot but the noise still come up. I tried another android phone and it is the same. I am going to try installing the app on an iphone and see if it is related to the way the phone sends sound to the unit. Help if you figured this out.
