Today suddenly, I get no sound from my right earpiece while using headphones (it works fine without them). My headphones are not the problem either, I just tried them with my phone and they play from both ears just fine. In 14.04 there was a persistent problem with Ubuntu where I would never get any sound while using headphones, but I never found the solution to that and assumed they fixed it in 16.04. Is this still broken? When I first noticed it, I immediately tried to test the sound and got faint sound in the right speaker that didn't increase if I moved the balance towards the right, but shortly after that I got none at all.
