I don't know if I pushed the "wrong button" or what, but all of a sudden I get no sound over the speaker in the box, only the headphones have sound. Doesn't work with the phones unplugged, and the volume control in control panels and in the taskbar are not set to mute. 98SE Thank goodness for this Forum - I recently discovered it and have already got a number of aggravating long term problems solved. Thanks so much for everyone's help!!!
