Front Panel Audio (Asus board; HD audio plug) not working

view story

http://ubuntuforums.org – So my board (ASUS Maximus VI Hero), has the standard front panel microphone and headphone ports. These are hooked up to a 10-1 pin AAFP, using an HD-audio compliment cord. The back ports, which are connected directly work fine, including the headphone port on the back. UEFI is set to HDAudio for this port, so that isn't the issue. Something I've seen in a thread, but haven't tested, is to set UEFI to AC97. This might be useful for finding the missing device, if it works. In sound properties, I see three devices: 1. HDMI / DisplayPort 3; This is my graphics cards sound, not an issue. 2. Digit (Hardware)
