I've had a 2018 Mac Mini for about 2 weeks now (i7/16/512) I notice a lot of what sounds like audio cracking when listening to music on Youtube in Firefox. I listen to in the background while performing other tasks. It typically happens while the CPU usage momentarily steps up in the foreground app but sometimes also happens when idle. I've never had issues before with these headphones before which I use on other devices. I also used these headphones in a nearly identical manner in a 2012 Mini with and other computers with no such cracking. I'm listening on wireless Bose QC 35 headphones over bluetooth if that matters. Has anyone else noticed this?
