I had sound and could record my input. Now it is gone. I have no idea what happened. I used it earlier today, and it was fine . I logged on tonight, and it doesn't work. I hear the "bells" (sound when you get an answer correct), but I can no longer input my voice. When I click record, it doesn't show the red soundwave line, or record my voice. PS, it never did work for me as far a me listening to it. That was always silent. Any help will be appreciated. Thanks
