Oops! Yes, that's what I meant.

Okay, the relevant jacks are "Front Headphone" and "Line Out Front". I
don't know if you're trying to use the headphone or the line out port,
but if you can disable jack detection for both:

In /usr/share/pulseaudio/alsa-mixer/paths/analog-output-
headphones.conf, change these lines:

[Jack Front Headphone]
required-any = any

to

[Jack Front Headphone]
required-any = any
state.plugged = unknown
state.unplugged = unknown

and similarly in /usr/share/pulseaudio/alsa-mixer/paths/analog-output-
lineout.conf change these lines:

[Jack Line Out Front]
required-any = any

to

[Jack Line Out Front]
required-any = any
state.plugged = unknown
state.unplugged = unknown

These changes will be overwritten whenever your distribution updates
pulseaudio (yes, this sucks, hopefully this will be improved some day;
I think George Chini already has something prepared related to
disabling jack detection).
