[Bug 874535] Re: Volume Slider Jumps, due to rapidly changing hardware jack sense state
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.

Title:
Volume Slider Jumps, due to rapidly changing hardware jack sense state
Status in “alsa-driver” package in Ubuntu:
Triaged
Bug description:
In Oneiric Release, The volume slider randomly jump down a notch or
two for fraction of a second, even when there is no audio playing on
the system. If mute is selected, the menu will quickly flip out of
mute mode and back again. This change actually affects the audio
output, resulting in pops correlated with the volume changes.
