I use a Focusrite Scarlett 2i2 3rd generation. It works fine, but you'll want to
read this post. Also the 2i2 makes a "click" in the audio output when switching sample rates; it's not loud enough to damage the speakers, and it's only when going from playing MP3 to Youtube (or to Reaper), so it's something that doesn't bother me. (It probably does that in Windows too.)
