Lastly, many onboard cheap soundcards such as SoundBlasters have this ability (although it often isn't marketed, or identified as usable in this way). Perhaps you can trade in your Scarlett 2i2, and upgrade to the 8i6?
I knew about the Sound-blaster cards, but I didn't know about the others...My comment about him asking Focusrite, was more to do with him implying that it is Props job to fix it.
Anyway - great post.
