First, thank all of you for offering suggestions. Second, I wish to share this information. My headphones are now working. They do not work from the Real Media Audio program but rather from the CD player that is built into my browser. As I have two CDroms, one for burning, and the other the one that came with the tower. I plugged my headphones into the latter one one. To the right of the portal are two switches for adjustments. You have to click twice on the one just right of the portal. The one over more to the right is to eject the CD. Of course, the one to the left of the portal is for the volume control. So simple? Yes, but when you are not hardware wise it was a real Sherlock Holmes problem. Thank goodness for my son, Watkins, the problem is solved , and I thank all of you for eliminating all the other propossed ones.
