I can't seem to listen to previously recorded tracks while recording a new track in Audacity. It says: "Error while opening sound device. Please check the input device settings and project sample rate."
This has been bugging me for a while, so any help would be greatly appreciated.
EDIT: I should add that I have two sound cards, and I can play to and record from each one. The problem only comes if I try to play back the previously recorded tracks while recording a new one. I have tried all combinations of the two recording/playback devices.
