I have a strange Sound problem. After every boot up my Sound works fine until I plugged in the headphone. 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.
