Default Front audio on motherboard

I'm trying to connect my front audio on my motherboard but when I connect the pins it doesn't work... got the mic to work though. I was using the manual for my mobo but the titles of each pin didn't match what the titles were on the black sticks that connect to it. Is there a standard as to how you would connect the front audio to the motherboard?

You just need to identify each lead to the plug on the mobo. Some connectors at incorrect, i.e. a 3 slot connecter when the mobo has 2 slots. For this, you need to use a small screwdriver and rearrange the leads.

There is, according to the pin diagram sheet from my Silverstone front panel:

For AC'97 Pinouts:
1 | 2
3 | 4
5 | 6
7 | 8
9 | 10

1: MIC IN
2: GROUND
3: MIC POWER
4: NC (Not Connected)
5: R-Out (Front right channel)
6: R-Ret (Rear right channel)
7: NC (Not Connected)
8: Key (pin blocked)
9: L-Out (Front left channel)
10: L-Ret (Rear left channel)

For Azalia Audio connections (never heard of it):
1 | 2
3 | 4
5 | 6
7 | 8
9 | 10

1. Port1 L
2. AUD GND
3. PORT1 R
4. PRESENCE#
5. PORT2 R
6. SENSE1_RETURN
7. SENSE_SEND
8. KEY
9. PORT2 L
10. SENSE2_RETURN

Your motherboard more than likely has AC'97, as that seems to be the standard. The first pinouts should work. Ground is usually the "other line" for the pins, so a left speaker would be connected to Left Front Channel and to Ground, etc.

Nah... still not working. The 97 codec that you show isn't the same as the one in my mobo manuals.. but either of them arn't working for some reason. The mic's work fine though. I have an nforce 680i lt sli and the case's front connectors are simply labeld rout, lout, ground, power, rret, lret. I know this isn't spose to be this hard. Anybody have any ideas about this board?
