I'm using iMicro SP-IM320 microphone/headset in my NUC D34010WYK. The installed operating system is Kubuntu 14. Speakers or headphones plugged into the regular speaker jack work fine. The headset/mike work fine also, as I've tried them in another computer. It seems as if the computer just doesn't recognize the headset. The USB ports are working, as I use flash drives in them all the time.
