Hey! I had the same issue with unblocked static last month. Turns out it was my Wi-Fi router causing interference. I moved it farther from my audio setup, and the crackling stopped. Maybe try relocating any wireless devices near your gear?
Also, check out this site called "Audio Issues Fixer" (audioissuesfixer.com). They have a ton of guides on troubleshooting unblocked static and other audio problems. Helped me a lot!
