I usually run sound from my laptop through my headphone jack into a mixer so I can listen to music through my big PA speakers. The moment I upgraded the OS, however, it stopped working when plugged in, no audio at all. Sound still comes through the laptop speakers when unplugged, though. I dual boot, so I logged into Windows and the sound worked fine. What should I do to fix it?
