To get sound out of my headphones, I need to unplug the headphones and plug them back in again. After this, sound is sent to the headphones. Reproducible: always Steps to reproduce: 1. Plug in headphones 2. Switch on computer, log into Kubuntu 3. Attempt to play sound in any application, no sound produced. 4. Unplug and replug headphones 5. Sound works Expected behaviour: At step 3, sound should be output through the headphones. The problem seems to be in alsamixer: when starting Kubuntu the headphone volume is set to zero and the headphones are muted. Re- plugging the headphones will unmute the headphones in alsamixer and set to an audible volume.
