[DragonFlyBSD - Bug #2090] (Feedback) snd_hda does not support headphone automute
Issue #2090 has been updated by Shane DragonFly.
File hda_automute.patch added
Status changed from New to Feedback
The attached patch shuts down all speakers when something is plugged into a headphone jack. This is done by enumerating the codec's widgets instead of using a static lookup table. This patch also removes polling for headphone jack insertion because polling was configured via the lookup table. If needed, polling can be re-added with a new sysctl which would correspond with how FBSD configures polling.

booted verbosely, there's no action, so attaching headphones does not mute
An update to FreeBSD's sound/pci/hda expressly mentions solving this problem:
