Preview sounds before importing

For some reason I cannot preview sounds before importing them. I could do this with Nuendo 5. Could this be due to bit rate mismatch? I am now using a 64-not system with Nuendo 7.

Double-check preferences - Control Room - Use Phones Channel as Preview Channel…?

That didn’t work. But after some trial and error I solved it.
