I never emded up fixing my problem actually. It cant be rytm related because when i listen directly from the hp out theres no clicks. I got my interface repaired (it was giving me a few minor unrelated problems) and turns out the was 1 dead and 1 live cockroach inside it (yes you heard it right). They did full testing on it and said its working perfectly but im still getting the pops. I also spoke to focusrite supoort and my next step is to temporarily replace the rackmount pre… Im going to just send that in to get fixed. Im almost certain its that. Ive been overseas and really busy so havent got the problem fixed yet :’(. Maybe ikl just connect directly to my interface. Ill post back when ive got more info
