Seeing the same thing Laptop HP dm4-1140SA, wind like / train going over track noise when earphones are plugged in.
After audio has stopped playing, about 30 seconds, the background sound stops. Once audio is played again the horrible background noise returns. Muting the microphones doesn't work.... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990605 Title: constant background noise sound after upgrading to ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/990605/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
