After I plugged in the headphone the Sound works for a shorter time and then gets stops working. I tried to reload the alsa but no use. Now the Sound is not working from both headphones and external speakers. Below is the list of playback devices.

Install pavucontrol (pulse audio volume control).

Run it . In the "output device" tab, try to manually change "port" from speaker to headphone (or reverse) .

  • Look in the "configuration" if analog profile is selected. Launch Alsamixer in a terminal to check faders state when you insert jack ( see wiki.ubuntu.com/Audio/Alsamixer ) . Anyway, you could try upgrade to 16.04...
