I will make it quick : I have no sound in my headphones when they are plugged in on my Asus F200CA running Ubuntu 14.04, but :
- I have sound in the laptop speakers when the headphones are plugged out.
- If I boot up my laptop on a Live USB running Ubuntu 14.04, I have sound in the speakers and in the headphones.
- If I open
pavucontrol, I can "see" sound, but I can't hear it.
I already did some of the actions listed here.
I'm running Ubuntu 14.04, with Unity, and this bug appeared about a week ago.
