Thanks to all who have helped here. I have read through the responses and tried different settings and have also had my son who knows far more about computers and such than I look at the responses. He now lives about 600 miles away so uses the Team Viewer Ap to fix things for us. He worked with us for about 45 minutes and finally got Audacity to record by switching the 'stereo mix' button to 'headset microphon'.   But Audacity recorded the conversation between Ben and I, not the music that was playing. One thing changed for the better and that was the volume level is now at a much higher and more satisfactory level. No satisfactory recording yet. I will keep trying. I am using Windows 7.
