My case has built in audio jacks on the front (mic and headphones) well for some reason the headphone jack doesn't work (don't have anything to test the mic jack with). On the inside it had a connecter that said "HD Audio" which fit perfectly into the slot on the mobo labeled "Front panel audio connector". However there's also a plug that says AC 97 that fits in there (and in the BIOS theres an option to switch between AC97 and HD Audio). Theres also one more thing on the same cable it's labeled Azalia and it's a bunch of single wire plugs. I really don't care about the audio other than being able to use my headphone jack so what do I need to connect???
