Thanks for your reply. Trying different settings I can now confirm that the crucial point is whether "Software Playthrough" is selected or not. When selected, sound is heavily distorted also in the saved file as reported above. (In german: Bearbeiten > Einstellungen > Audio E/A "Software Playthrough (Neue Spuren während der Aufnahme mithören)".
It doesn't make any difference if mono or stereo recording is selected. With this settings it is possible to listen the sound before and during recording. Only a faint 50Hz-buzz accompanies the recording.
