Front audio not working

[synixx]

Hi, i've plugged in the cable labelled audio to the HD_AUDIO header (or whatever it's called but still no sound from the front audio port. It doesn't even register that my earphones are plugged in. The USB ports are working, so i'm a bit confused. My mobo is an Asrock ALiveSATA2-GLAN (http://www.asrock.com/mb/overview.asp?Model=ALiveSATA2-GLAN)

All the back panel stuff is working.

PS. How can I link a URL using words? Like having 'ALiveSATA2-GLAN' and when i click it it takes me to the web page.

Thanks.

I use HD, i changed auto to enbabled in the bios.
I do use realtek software. I tried what you suggested a few times without success. Might try again later.

When i plug my earphones in i hear a crackling sound, not matter wether the speakers are plugged into the back apnel or not. any other ideas?
