I have been having this problem for quite some time and finally i found the solution. To those of you out there who’s using Realtek audio as well as Vista operating system, if you encountered this issue of having the front panel audio jack not working, then this is a possible solution. I don’t quite understand why by enabling the ‘disable front panel’, it will work, because you’re suppose to enable it, but then you check the box to disable it, means you want it disabled, but then again, it works! So who cares? 🙂
Here’s a more detailed explanation taken from one of the forums out there:
Audio output was dead on one of my media centers after updating to Vista SP1. (Otherwise the 2 updates went fine.) I’m posting the solution here as it might save someone else some trouble.
My configuration is:
Realtek ALC883 HD integrated Audio
Speakers were plugged into the front panel which is connected to the motherboard in AC’97 mode
(Rear panel audio – unused – had HD jack detection turned on.)
After the SP1 update the Sound Manager window showed “Realtek Digital Output” enabled and “Speakers” (the analog output) greyed out with no way to enable it.
Eventually I worked out SP1 had reset all audio settings including the setting “Disable front panel jack detection”. As the audio manger could not detect any cables in the rear panel and jack detection would not work from the AC’97 connected front panel, it disabled the analog Speaker device.
The solution was to check the “Disable front panel jack detection” option. (This option is well hidden under a small unlabled folder icon on the right of the Gigabyte HD audio manager panel.) This turns off HD Audio mode jack detection and forces the motherboard to support AC’97 Audio mode for the front panel. The speakers worked again after making this change.
This was only an problem for me because I was using the front-panel connectors. Had I been using the rear panel, everything should have worked fine after SP1. It just goes to show that Microsoft really has their work cut out for them to cover all the possible configurations that are out there.
And here’s the pic showing exactly where to access Realtek Audio Manager to check ‘Disable Front Panel Detection’.
Hope this tip is useful to anyone out there facing similar problem. 🙂

For those who don’t see the folder. You have to go in your BIOS and go to Advanced Settings or just Advanced –> Chipset Configuration –> Enable Front Panel and set this to Enable if you have as Auto or Disable. Hope this helps!
