Yes its on.
I don't know if the right port. But it is plugged into the purple hole on my computer. I followed a youtube tutorial for hooking up my stackmat timer for CCT.
It doesn't work correctly with CCT, like random numbers would keep displaying, but it would definately recognize my stackmat timer because it was only when I turned on my stackmat timer that this problem occured. I was going to try and fix it but then I found this timer and I l ike this a lot better
I'm not sure about recording sound. But when I make youtube videos via youtube's option of recording a video, my webcam lets me record sound in the videos. Not sure if htats what you were asking though
