Headphone is not working for ubuntu 14.04
I just converted into ubuntu 14.04 from windows and the speakers on my laptop are working fine. Although when I tried to use my headphones the sound is still coming out from my speakers. I looked at my sound settings and I cannot find the headphones icon. Already looked through the alsamixer and set all volumes at at high and unmuted everything.
Solution 1:
From Windows , do a real shutdown (not reboot) and retest.
If not ok, disable "Fast Boot" (see this answer)
