I'm going from cassette tape to the computer. When i click on "record" the green bars start hopping around and in playback I can hear, clearly, what was recorded. But I cannot get any sound while it is recording, only on playback. Tech support said my noise floor was too high but I've reset it to their suggested -40 and then experimented with several other settings. Same results: it records ok but I cannot hear it while it is recording.
