Hi Yiddo69,
This is a strange problem, but a couple of thoughts come to mind.
1. Just double check that your headphones or speakers or whatever you are using to listen to your recordings are not the culprit (ie, only partially plugged in or something).
2. If you run the recording wizard (left-most button on the main toolbar) are you getting a good signal on both channels when you get to the "Recording Volume Calibration" screen?
3. If you listen to the recordings immediately after you have made them and *before* you run any of the "Audio Restoration Tools" options, do you hear stereo or mono?
4. Can you open one of the recordings in WavePad using the button from the toolbar and check what the file properties are? You should be able to see this in WavePad on the bottom info bar - you should see the sample rate and number of channels.
Regards,
Ben
