I'd say noise on the sound is due more to other things than "EM
radiation", such as:  Hash on the power supply, which can still affect a
USB device if it doesn't adequately filter the supply.  And using a
common signal earth between audio and other things, which can still
affect a USB device.  Not to mention the processes that generate audio
being interrupted by whatever else the computer is doing.

I eliminated most noises on the sound using the simplest of methods:  A
couple of audio transformers between the sound card and what I plug into
it.  It electrically isolates them.  You can get such things, on the
cheap, from many retailers which sell car audio products.
