I’m the network technician for our company, which is a medical group. One day one of our doctors said he was having trouble with his speakers. My supervisor, the Network Admin, was on site and he said he would take a look. After 15 minutes of tinkering with the volume and other settings under the control panel, he gave up and asked if I would take a look. He suggested reinstalling the audio drivers as a last resort.
I reached down and clicked the speakers on…problem solved.
They both turned red and said how stupid I had just made them look.
