Connected Turntables...Now ordinary soundcard won't function

I bought a new turntable, connected it using one active turntable through the MK46, now when I disconnect the mk46 and just want to play around with my headphones through my laptop soundcard, i get no sound at all. here is my configuration report. I've never had a problem like this and I've restarted the program and my computer to try to solve it. Any hints?
