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 Alcc then I’ll use AC97 connector.
The standard was used in motherboardsmodemsand sound cards. Retrieved from ” https: On HDA audio to the front and rear outputs comes from seperate outputs on the audio codec. Just to note, there’s a third kind of connector i came across, labelled azalia – which is a bundle of loose connectors.
They are usually small square chips with 48 pins pin QFP package.
Adding this as a comment in case someone comes across it. 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 ac9 wire.

Your particular front panel looks to me like it is primerally designed for HD audio motherboards but with a hack to give limited support for Ax97 boards. The correct one to use depends on your case. A minor part of those standards is a front-panel audio connector. The linked articles have more detail on that.
