i'm using digidesign's digi 003 rack version. it works well, but it's quirky. one of the quirks i'm sure hoping i can find a way to fix. for no apparent reason, sometimes the core audio manager can't find the digi 003. the audio manager says the 003 is in use. by what, i have no idea. thus, to use the 003 again, i have to shut everything down and restart. my computer automatically shuts down each night and restarts each morning. the first time i tried to play some audio, i had this problem. does anyone else have this problem or a solution? i have followed (begrudgingly) digidesign's requirements regarding energy saver settings. thanks.
