Hi If it’s a sub $1 device, it’s pretty much guaranteed that it has digital “stuff” inside it. That circuitry will generate blips and pops totally independent of any attempt it makes at compensation. If it “wakes up” this or that digital sub section every 107.34 seconds, you get an internal current spike. Spike hits grounding on the board ( or the supply) and the output moves.
There are dozens of other possibilities. Just like the one above, all of them require a knowledge of what’s inside the part. Taking a hammer to it would be the first step ( = remove the lid :) ). Getting a full schematic and the specs on the chips inside would be a somewhat deeper dive. Dumping the programming information on top of all that ( = you have the layout of the PCB, the schematic, the parts list and the specs on the parts) would top off the “need to know” details.
