Thanks! I tried shorting pins on Audigy with no luck. But i got everything working using onboard soundcard. Now i got another problem. When playing with core and DIN modules, I accidentially put one of the DIN modules on some metal bridges. I think it shortened something. After that i got following problems: + LCD is not working, when DIN is connected. + When DIN is not connected, I get wrong symbols on display. Could it be because of some burnt resistor or other component? EDIT: When left alone with no power for some time (quite long time), CORE boots normally displaying normal text, READY, not RAA@Q
