I have done it, and many others have done it. All sand will turn live when live rock is present, and will get seeded with pods and beneficial bacteria.
As to using play sand, you would *really* need to rinse it out. I have seen a few tanks that use play sand, but many others that use regular aquarium sand. And make sure the play sand is not open when you buy it already, just to make sure it is not contaminated.
