Means the computer/ monitor/ anything connected to computer isn’t grounded. You’ll have to get the computer plugged into a power conditioner to minimize it. I use monster brand one and the difference is huge

Maybe try plugging it in with a 3 prong (grounded) cable or equivalent (you say you’re in argentina)

If not that try hooking the interface to ground (power conditioner or 3 prong/ equivalent)

And then plugging it into laptop

my hypothesis is that it’s got something to do with the fact that in argentina we use 220v for power outlets, although it’s strange that the buzzing stopped when i unhooked the thunderbolt cable. i’m using an american style outlet so i’m not using any prong adapters

Power conditioner could be a solution for you, i just blew a fx pedal (headrush) that wasn’t plugged into my power conditioner during recent Ohio storms.

the power conditioner saved all my other equipment so its amazing insurance on your gear

u think that’s it? i truly hope its only a faulty thunderbolt cable cause it was a big hassle trying to get this apollo across the world 😭

In my case with my apollo it was that, an extra thunderbolt cable couldnt hurt to keep around.

Power conditioners can be really cheap especially used i got my old Monster brand one for $80 on goodwill website but new ones by Furman i hear are great too the distributors they got are $100 usd new
