Speaker works but headphones don't

Question

I'm using Ubuntu 13.10 on a notebook Asus X450C, My speakers works fine, but, when i try to use headphones, the sound stops, but if i remove the headphones, it keeps playing normally

Answer 1

I had the same problem for days, but on Trusty (14.04). The solution was to do the following two things:

1. Reset user configuration (as described in the Troubleshooting section of https://wiki.ubuntu.com/PulseAudio);

2. Make sure Independent HP is Disabled in alsamixer. To do that, just type alsamixer in a terminal, then choose your sound card (by pressing F6) and move to the Independent HP column.

Hope it helps!

Answer 2

When pluging in your headphone check the system volume, it may drop itself to zero. If it is not at 0 then open the sound menu from settings, or just click sound on the the dash and change the output to your headphones. I have the same problem. It may also work in reverse headphones out and no speaker.
