Thank you (and robot1). I installed pavucontrol and followed your instructions. The volume was selected in the middle (100%). We see a volume meter going up and down as expected with either headphones or speakers selected. When mute is pressed the meter looks dead, as expected. It also shows line-out is unplugged and headphones are plugged it. Any thoughts. I appreciate the help. allan
