Focusrite 18i20 ground loop? - forum Audio & music gear
However, when I plug the laptop in, I get some nasty audio feedback and haven’t been able to resolve the issue by plugging the devices into separate wall outlets, etc. Is this summed up as a use not intended for the 18i20 or are there any suggestions?
The laptop dock has a TRRS jack so I have a splitter plugged in and the cables plugged into the the audio in/out of the 18i20.
