Tia The AAFP 2x5 header is not the same as previous FP_AUDIO headers. There are no return lines, and there are fewer wires to be connected. For AC97, use Line_out_R, Line_out_L and the AGND signal, to run headphones. For a microphone, use MIC2, MICPWR, and AGND. No connections are required to the other pins on the header. If you have wires left over, from the front panel, leave them unconnected to anything. This is the current version of the Intel I/O spec. Page 21 shows the AC97 definitions. http://www.formfactors.org/developer\specs\A2928604.pdf This is the only copy I can find of the original AC97 header definition. Notice how Intel just changed a few of the pin definitions. http://www.minmaw.com/FPIO_Design_Gu...inal%20v10.pdf Stick with the Asus pinout information in the manual, and you should be able to get the headphones working. If you still cannot get a signal from one of the channels, you may need to RMA the board under warranty. HTH, Paul |

hi paul
i have this chassis : http://www.thermaltake.com/xaserCase/Damier/v6000a.htm look at this ual USB2.0, IEEE1394 Firewire, audio & speaker ports = 2 jacks = ac97 (no HD audio) ? tia |

re
i have connect for HD audio front panel but i have only two jacks (pink, green ) in this front panel ! http://www.asuscom.de/pub/ASUS/mb/so...ad2premium.pdf page 49 the correct connection was ac97 front panel audio pin définition for my front panel with 2 jacks ? tia PS : it's hard to put wires in this audio pin !!! |

Yes, you should be using the AC97 audio pin definition. Remember to select AC97 definition in the BIOS "Front Panel Support Type" on page 4-27. MIC-IN --------- MIC2 X X AGND -------- GND MIC-VCC ------- MICPWR X X NC EAR-R ----- Line_out_R X X NC NC X EAR-L ----- Line_out_L X X NC There will be an EAR-R and an EAR-L left over and they should not be connected to anything. Only one EAR-R and EAR-L need to be connected, and the others can be left dangling. HTH, Paul |

hi paul
i've connected same at 3.4 of http://www.thermaltake.com/support/i...sis/Damier.pdf page 12 MIC-IN --------- MIC2 X X AGND -------- GND MIC-VCC ------- MICPWR X X NC EAR-R ----- Line_out_R X X bline out R = disconnect that ? NC X EAR-L ----- Line_out_L X X bline out L = disconnect that ? bline out are useless ?? tia |

NC X EAR-L ----- Line_out_L X X bline out L = disconnect that ? bline out are useless ?? tia If you look in the Asus manual for the P5AD2, the bline_out pins are no longer provided. The Azalia sense lines are connected there now. The old way of doing AC'97 was like this: (The Damier case doesn't have the switch, and shorts the line_out and bline_out together.) \ headphone_mute_contacts ___. \.___ (switch opens when headphones / \ are plugged in) | | sound_chip----X X-------------- rear_lineout_connector line_out bline_out The old way of doing things was for some extra contacts on the headphone jack on the front panel, to mute the output of the rear (lime colored) lineout jack on the back of the computer. When the headphone was plugged in, the "switch" shown above opens, and then sound no longer comes out on the rear lineout jack. I suspect the Azalia AC'97 header looks like this, because otherwise there would be no way to get a signal on lineout on the back of the computer. \ headphone_mute_contacts ___. \.___ (Not connected) / | sound_chip--+----X X +------ rear_lineout_connector | line_out nc | | | \________________________/ (wired inside motherboard) What this would mean, is the rear lineout connector would not have a mute function. The headphone and the rear lineout would always have a signal on them. The extra contact would not be needed. Please test this function and report what you find. I.e. With the extra wires unconnected to anything, plug speakers into Lineout on the rear of the computer, and see if they get a signal while the headphones are also plugged into the front of the computer. That will prove or disprove the theory in the second picture. By the way, your Damier case does not have a mute function, and the bline_out and line_out are shorted together permanently, so that there is a signal on the headphones and the rear lineout all the time. Some other computer cases have the headphone_mute_contacts shown above, and then the line_out and bline_out use completely separated wires. HTH, Paul |

The C-Media 9880 chip has eight stereo general purpose ports on it. Two ports would be used for Mic_in and Line_in. Four ports would be used for front, rear, center/sub, and side speakers. That leaves two ports. The motherboard itself has a "CD" audio header, leaving one port. It is possible that the one leftover port is used solely to drive the AAFP header headphone output. But only by testing (plug in headphones, listen to see if lineout speakers on the rear of the computer are stopped) will we know if that is how Asus hooked them up. Paul |
