I'm having the same problem
I'm gonna wait and see first as don't really have the money to buy another soundcard!
As a more general observation, unfortunately PlayIt Live (unlike some other audio programs) doesn't see all the outputs on 7.1 or 5.1 sound cards and PlayIt Live no longer supports Asio4All.
For good or ill, you need a card with a manufacturer supplied driver (such as the ESI drivers).
For many applications the ESI UDJ6 will suffice and the drivers seem good.
