bob is right, that indeed does work.
However I have also to say:
DVS is very expensive. Not because of the sound card or decks, because of the upkeep.
Expect at least 80-100 bucks per month to spend on needles, heads, control vinyl,…
So whatever you try to accomplish, think first if it is not much easier to do on a controller anyways.
See me for example, I relied very long on scratching on vinyl until I got the Terminal Mix and actually I can now easily do any scratches I want on the controller.
Check out our Scratching for controller DJs course if that interests you, it is money well spend and will prevent you to blow loads of money on record decks and gear (that now rests in my basement or I sold off on eBay.)
