Bug Description
When I connect the headphones, there is a strong hissing in both left and right side. It does not amplify or reduce along with the master volume. Instead, if I completely mute the master volume, the hissing disappears. It comes back as soon as I unmute the master volume.
The internal speakers of the laptop are not affected: when headphones are not connected, there is no background hissing noise.
Standard four questions:
1) Ubuntu release: 14.04 LTS
2) Package affected: kernel? (linux-
3) Unless I play music, I expect no to hear anything in the headphones
4) I get a background hissing noise in the headphones
Thanks!
