I had an unsuccessful experience trying to get HP Hardware to provide me with the pin-out configurations. I was transferred 5 times trying to get someone to help me. My laptop is less than 1 year old and still in warranty. Since I can't get any help there does anyone have the pin-out for their single port headphone jack? I'm trying to feed signal into a RF digital communications interface such as a Signalink or Rigblaster plus.

You might try to download the service manual for said computer...from the HP website.

Louis, Thanks for your input. I did search the service manual and the information on the  Audio jack pin-out configuration was not detailed in any way. That was why I placed the call to HP support.

I'm no expert in this regard but isn't the jack pinout a standard for a 3.5mm headphone? Or are you looking for the pinout of the connector on the motherboard. I was doing some searching for the motherboard schematics but it only led me to some paid sites.

Hi John, Thanks for your reply. That's what i'm trying to determine. HP went from a dual set of 3.5mm jacks that accommodated mic inputs and audio outputs. Usually the mic input was a 3-conductor jack and the audio out was a 2 conductor jack configuration. Now on the newer HP laptops there is only one jack. I assume this one jack has more than 3 paths and that's what I'm trying to determine so I can wire my digital interfaces correctly.

I have no information on the combined 3.5mm jack you are looking at, but it may be simpler to consider using a cheap USB audio interface with standard (possibly phono/RCA) connections for your requirement.

RQT, I was looking at a USB interface but it also had a sound card built into it and to me that was overkill aince the laptop and digital interface both already have built in soundcards. That may be the route that I'll have to take.

HowtoGeek talks about the single jack. I will try to find the schematics on the motherboard if possible.

Thank you.

Now I know how a Bose headset user feels when he has to use a Lighting adapter on his new iPhone 7.

Not having much luck tracking down a schematic. Seems like everything found requires a premium account.

John, thanks for putting time into this. If I can't reverse engineer this I may have to spring for premium support.

Take care.
