This question explains the electronics of the problem, and several solutions to fix it by DIY'ing a solution. I am worried that these crazy loud pops will damage my speakers. I run into this problem when plugging in a new source (phone, laptop, tablet, etc.) into some PC speakers (analog, or with a USB-C dock or adapter).
I'd like to buy a cheap little adapter thingey and put them in several places where I encounter this issue to protect my equipment. I was able to find some ground loop isolators on Amazon for about $8, and they are solving another, different, problem that I run into. They partially mitigate the insertion-popping problem, but there is the inevitable cackling and popping if the cable moves even the slightest, which is not at all mitigated by the ground loop isolator, and can also damage my speakers in the same way.
Does such an off-the-shelf product thing exist? If so, what is it called?
So far my searches are getting crazy results, including on page 2 stuff related to plumbing (?!?). I'm not sure what's up with that, so I figured I'd ask here. Yes this is related to PC hardware, as my PC speakers have a 2nd input specifically for these purposes. Klipsh and Altec Lansing mostly.
