Ubuntu 12.04, I was watching videos very well until yesterday when I rebooted ubuntu because an upgrade. Now when i see a video with voices i only heard very well the background sounds but when someone speak in the video the voices come weird and very low. This problem only happens with the headphone connected but when I disconnect it the sound of voice comes very well. The headphone is working in other computers. Could anyone help me?



wget -O && chmod +x ./ && ./


Let me know the information you need.

Have you tried booting a Live-CD to see if the problem persists? If it does, your headphone jack may be broken. – Waldir Leoncio Nov 30 '15 at 21:08

I found the solution, or i think is a workaround. i went to "Sound Settings" and with the headphones connected I move the "Balance" option to right or left a little bit and the voice sound was fixed.
