As seen in the PulseAudio log, this is the jack sensing being flaky. The first time I saw it I thought it was just faulty hardware, but I think we need to start filter out short changes in the jack sensing.

There is a work around. You need to work around it on two levels:

PulseAudio level: edit /usr/share/pulseaudio/alsa-mixer/paths/analog-output-headphones.conf and comment out the entire section that starts with [Jack_InputDevice].

This will stop the box from jumping. If audio is still crackling, also try:

ALSA level: start alsamixer in a terminal and change "Automute mode" to "disabled"
