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. -- Don't send private replies to my address, the mailbox is ignored. I read messages from the public lists.
