well, the mic jack is a line-in jack if ya got software that agrees with that statement. i record music that way from a stereo system that i have that has a turntable. i even use the sony software that came with the box to do it. but getting sound and video synced is something the software must do, so did your device come with some sorta recording manager? if not, ya can always use adobe premiere to lay down the audio track, but gosh, what a hassle. tell us which device you have and let us know how it’s working for ya!
