When I connect the headphones, there is a strong hissing in both left and right headphone. It does not amplify or reduce along with the master volume. Instead, if I completely mute the master volume, the hissing disappears. The internal speakers of the laptop are not affected.
1) Ubuntu release: 14.04 LTS
2) Package affected: kernel (linux-image-3.13.0-24-generic)
3) Unless I play music, I expect the headphones to be muted
4) I get a background hissing noise in the headphones
Thanks!
