Public bug reported:
I use the following:
Motherboard: Zotac Z68ITX-A-E
(http://www.zotacusa.com/zotac-z68-itx-wifi-z68itx-a-e.html)
Case: Lian Li PCQ08B
(http://www.lian-li.com/v2/tw/product/upload/manual/PC-Q8.rar)
I have had issues getting the front panel headphone jack to successfully
work. The connection works just fine in Windows 7 Ultimate. In Windows
7, the installed Realtek ALC892 Codec drivers are able to sense when a
device gets plugged into the front panel jacks. I have verified through
the manuals that the Motherboard Front Panel Audio is spcifially HD
Audio and the Case Front Panel Audio Plug is HD Audio plug.
I have tried the latest linux drivers from Realtek (5.17rc1) from the
realtek website to no avail.
If there is anything more that I can provide please let me know.
PS. Additionally I am providing the Windows 7 Ultimate screenshots for
the actions "plugged in" and "removed" along with the Driver
information.
I've performed a sound-tone test where I've answered that the sounds works
because my rear-panel sound output works splendidly (front/center+sub/rear, no
problem).
Front Panel HeadPhone jack however doesn't do anything at all.
Here are the required info:
