I am using an Aardvark q10 Pro, Cool Edit Pro. i have all of the drivers for the Aark. I have been using CEP and Audition for several years. I recently picked up a computer that was custom built around the time of the manufacture of the Aark and was prestine when i got it. The computer is solid. I have had the Aark for a year and this is the worst trouble that it has given me. Here is the situation: Sometimes i can get playback through the aark. sometimes i can get playback but no click from CEP. a week ago i did some tracking and saved a session. every session that i try after that day i dont get playback at all. this happened in the middle of recording another sesion. also, my channels on the aark have skipped by three. track one is recorded through track 3 etc. if i open the "good session" i can rename and save under a different session however, i can not adjust the metronome or any of the settings without CEP terminating. i am going to uninstall the driver, and the recording programs. i will attempt to get this thing going from the ground up. any suggestions? thanks a ton, ri.
