Issue #2090 has been updated by Justin C. Sherrill.
I could not get it to automute on my machine:

Sound plays out of the computer speaker, and plays out of headphones when they
are plugged in, but the speaker is unaffected by plugging/unplugging the
headphones. The 'nid' showing up at module load is different; perhaps I have a
slightly different chip?

Bug #2090: snd_hda does not support headphone automute

Target version:
The hda sound driver does not notice jack insert/removal events. Even when
booted verbosely, there's no action, so attaching headphones does not mute
speaker audio.
An update to FreeBSD's sound/pci/hda expressly mentions solving this problem:
