Headphones don't work after update
Solution 1:
This is a temporary solution that works for me:
In Terminal type alsamixer, there is a volume bar for headphone. Switch in on by pressing M
Solution 2:
Having the same problem. I can correct it with the alsa mixer, but it reverts as soon as I unplug/plug back in the audio jack To make Audio jack have an output I actually have to turn up the SPEAKER output on the Alsa mixer
