My Kubuntu 14.04 also suffered from this problem. But the next seems to solve it:
in /etc/pulse/client.conf uncomment "Autospawn" line and change it to "Autospawn = no" and save Then stop pulseaudio by the next command: killall pulseaudio And restart kmix to switch it to new configuration. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874535 Title: Volume Slider Jumps, due to rapidly changing hardware jack sense state To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/874535/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
