[alsa-devel] [PATCH] ALSA: hda - Disable Front HP jack detection on Gigabyte Z87X-UD3H

[David Henningsson]

This motherboard seems to have a flaky jack detection - when the
front HP is not present, the jack state quickly switches on and off.

This has been reported by three people in the bug, so I doubt it's
a user error this time.
