Hi, I have been using the audiophile 24/96 soundcard with vista and usually cep2.1 to record and edit. just recently the external setting stopped working, all i get is a the red flashing 'unlocked' signal and constant hiss through the speakers when the DAT player is connected through spdif coaxial. however, play back through 1/2 inch connections works fine. any help would be great. thank you!
