I would suggest commenting out all "[Jack Headphone]" and "[Jack Line Out]" sections from the files in /usr/share/pulseaudio/alsa-mixer/paths. Unfortunately, any changes that you make will be overwritten whenever PulseAudio gets updated. I think it would be good to be able to override these files in /etc, but currently that's not possible. -- Tanu
