Just to follow up on this, as per the nice folks on #pulseaudio, it
doesn't seem pulseaudio is capable of this yet, so I created:

https://bugs.freedesktop.org/show_bug.cgi?id=68286

It can be worked around by using amixer to modify the hardware
controls directly. For my card (HDA Intel PCH with Realtek ALC898
chipset), here are the scripts I use:

1) enable speakers:

#!/bin/sh
amixer -c 0 sset "Auto-Mute Mode" Disabled
amixer -c 0 sset "Headphone,1" mute

2) enable headphones:

#!/bin/sh
amixer -c 0 sset "Auto-Mute Mode" Enabled
amixer -c 0 sset "Headphone,1" unmute

I know this was from over than a month ago, but anyway.... you can use something like this in a single script to toggle auto-mute:

#!/bin/sh

# check auto-mute state

amixer sget 'Auto-Mute Mode' | grep Item0 | grep -q Disabled

# $? is 0 if auto-mute is disabled

# $? is 1 if auto-mute is enabled

if [ "$?" -eq "0" ]; then

# unmute the headphones and mute the speakers

    amixer -c 0 sset "Auto-Mute Mode" Enabled
    amixer -c 0 sset "Headphone,1" unmute
else

# mute the headphones and umunte the spearkers

    amixer -c 0 sset "Auto-Mute Mode" Disabled
    amixer -c 0 sset "Headphone,1" mute
fi
