Question : Problem: Front audio port does not work

I built a competer using a Biostar TA7800 series board.  The front panel has a HD audio connection. The rear (motherboard) ports work fine but the front panel port will not work. There must be some BIOS or OS setting I am missing. All the HD drivers are installed and work correctely. The MOBO used the Realtech HD driver. I appreciate any help I can get.
Thanks, David

you should use the AC97 plug; then look in the bios for the audio setting, ansd set it to AC97
