It is recommended that you look at your motherboard manual. The header on mine is just labelled audio. If you wanted to use an AC97 motherboard without front panel audio it was nessacery to put jumpers on the audio header to make the rear audio output work. There are loops of wire on the AC97 connectors which will make the rear output work but it won’t be switched by the front panel connectors like it would be with a proper AC97 front panel.

Intel provides a specification for that header; the signal assignments are different for AC’97 and Intel High Definition Audio headers. They are usually small square chips with 48 pins pin QFP package.

I’m not sure of the exact different I assume that HD audio will gives better audio quality but I’ll always go for HD audio if the mainboard has it, if the mainboard only has AC97 then I’ll use AC97 connector. Incase your case only has HD connector but your board only has AC Just to note, there’s a third kind of connector i came across, labelled azalia – which is a bundle of loose connectors. If you plug an AC97 front panel into a HDA motherboard then plugin detection will not work correctly, it may detect devices as not present when they are present and vice-versa and the exact results may depend on what audio is playing.


Computer motherboards often provide a connector to bring microphone and headphone signals to the computer’s front panel with standard color jack.

HD Audio is intended to replace AC’ This apparently seems to be for systems with non standard HD audio implimentations. On the other hand HD audio cables have a wire and terminal connecttor lurking there, waiting silently in that cold dark hole poised and ready for the time when a naive unsuspecting pin 4 who isn’t even old enough to leave his motherboard slips into the High Definition Audio clutches of that extra wire.

The specification covers two types of component, and the “AC-link” digital interface between them: HD Audio is generally more capable.

The matching connector on your case should be labelled accordingly, I know mine is labelled HD Audio.

In other projects Wikimedia Commons. They both appear to have the same kind of connector right down to the ‘key’ – the space where there’s no pin and its filled upapparently the same colour codes at close inspection and so on.

Wikimedia Commons has media related to AC’ The pins that were previously used to loop back audio from the front are repurposed as connector-detect pins. On HDA audio to the front and rear outputs comes from seperate outputs on the audio codec. Home Questions Tags Users Unanswered. Ca97 panel audio design in conjunction with motherboard audio header design is dependant upon the type of audio CODEC qc97 used on the motherboard.

AC97 is supported by most operating systems, such as Windows and Linux. From Wikipedia, the alv encyclopedia.

Adding this as a comment in case someone comes across it. On some motherboards it may be possible to disable the plug-in detection so they can work better though still not perfectly with an AC97 front panel.

However the connectors are only semi-compatible. The link carries a bidirectional serial data stream at a fixed bitrate If more specific information is needed, i’ve a,c the motherboard from a dell into a cosair graphite T, just to test the case pending the rest of my hardware.

This capability depends on the codec.

The linked articles have more alcc on that. This is therefore a time-division multiplexing TDM scheme. The specification covers two types of component, and the “AC-link” digital interface between them:.
