RMA the card if it does not do what you were expecting the card to do, or if the card no longer does what it was doing before. Simple as that.
If it worked before then you know it can do what you expect the card to do
That it no longer does work in that manner means either you have changed stuff around, or the card is broken.
If you are able to recreate exactly the same setup you had when the card worked before and the card still does not work then the card is broken.
RMA time.
