I do know a few people in the past who have just bought a usb sound device because they want to use a mic as well, and that just didn't work quite right for them, even if sound output worked they had issues as soon as they tried using mic. I forget which, 4.1 or 4.4, 1 guy mentioned still using it just because output/input worked flawlessly. ¯\_(ツ)_/¯ -Dean
