Do headphone ports trigger udev events?

I'd like to write a udev rule to mute external speakers when I plug a headphone into the motherboard port. I am using

 udevadm monitor -k -u -p 

to look for events but nothing is showing up. Is there any way to accomplish this or am I out of luck?

Potentially relevant information:
Computer: HP DX7 laptop

[ryantr@lappy ~]$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05)
01:00.1 Audio device: nVidia Corporation High Definition Audio Controller (rev a1)

[ryantr@lappy ~]$ pacman -Q udev
udev 171-2

[ryantr@lappy ~]$ pacman -Q kernel26
kernel26 2.6.39.1-1

AIUI, ALSA doesn't trigger such udev events.

However, ALSA should be muting the external speakers - so file a bug at ALSA's bugzilla.

Would pulse-audio affect how ALSA handles it?
