For some odd reason, on my laptop, my headphone jack isn't working in Ubuntu. I obviously plug headphones into it, but no sound comes through them when I play something with sound. My headphone jack worked before in Ubuntu, but a few days ago, it stopped working.
My headphone jack works fine in Windows 7 (I have my laptop in dual-boot between Ubuntu and Windows), so I know it's not an issue with the headphones or the laptop.
Can anyone help?
