I can use the studio plug in to play back stuff. but i cant record anything without getting an error saying word to the effect od "the sound card is in use, check none of the tracks are using it". I'm sure the card isnt in use, cause the only software open is cool edit.
Any ideas?
Well, in order for anyone to sort out your problem, they'll need more information about your system...
But without knowing more, I'd suspect the soundcard or its drivers - For starters, do you know for certain that your card is capable of full-duplex operation?
