Re: MSI motherboard, Front Audio Panel for headphone...
On this motherboard you can enable or disbale the rear panel audio using jumpers on the motherboard. The jumper is labelled JAUD1. I'm assuming that if you select the rear panel, then the front panel will not work. This info is on page 36 of the PDF manual which can download from MSI. Good luck, the link to the manual follows:-

1. check if your front panel is connected to your motherboard at proper port2. check "expert mode" on your via hd audio deck, click "advanced options" and check "redirected headphone" (THIS WILL UNCHECK "INDEPENDENT HEADPHONE") and uncheck "enable front panel jack detection" this should solve your problem.
Surely your headphones are working fine. So it can be either software or hardware problem.
To check if any problem with drivers, go to device manager, uninstall the drivers for audio, and reinstall a fresh piece of audio drivers. Restart the system and now check the sound. If the problem exists, then its hardware problem.
Since front panel and back panel are not working, then it can be the problem with the audio sockets of the motherboard. You have to consult a technician for that.
Hope your sounds get ok with the driver install. Thanks
Your Intel DG33FB board by default was already setup for use. Your board has been configured for independent multi-streaming 5.1 audio (using the back panel audio connectors).
Your board should have come with a shielded front panel audio cable to connect front panel audio as shown on page 45, item B. The pin out for the front panel audio header is shown on page 46, table 5.
If you did not receive this cable you may need to contact Intel.
Check the Intel link included, which shows the cable needed for either AC'97 or HD cabling; Audio standards: AC'97 and HD audio
Most motherboards will not play audio through the rear jacks when the board is connected to the front audio pins. Intel like other manufactures do not mention this in their manuals.
Are there FRONT audio jacks you are trying to connect your headphones/mic ?
Dit it work before ?
First install all (incl. audio) drivers and try to get audio from BACK connectors (Green is speakers/headphones, Pink is Mic.)
If it workson on REAR, but not on FRONT connectors, check if you have another icon for AUDIO settings in Control panel and try to set FRONT audio settings.
Check if FRONT audio connectors are connected to your motherboard.
The headphone jack up front may not be connected to the PC's integrated audio on the motherboard (or to the PC's sound card if you purchased one with the system instead. There'll be an audio cable running from the front of the computer to a port on the motherboard. If you look at this motherboard diagram for the Vostro 220 (not the 420 or 220s), it'll be the port numbered "15" that's the opne for the audio for the front panel.
You don't need the speakers plugged on the back to have the headphones work, but having them plugged in will at least tell you if the sound is working or not.
Audio Ports These audio connectors are used for audio devices. You can differentiate the color of the audio jacks for different audio sound effects. Line-In (Blue) - Line In, is used for external CD player, tapeplayer or other audio devices. Line-Out (Green) - Line Out, is a connector for speakers or headphones. Mic (Pink) - Mic, is a connector for microphones. RS-Out (Black) - Rear-Surround Out in 4/ 5.1/ 7.1 channel mode. CS-Out (Orange or Yellow) - Center/ Subwoofer Out in 5.1/ 7.1 channel mode. SS-Out (Gray) - Side-Surround Out 7.1 channel mode.
