I bought a new HP but there is no documentation about what this is used for. Anybody know?

Looks like an old style Audio output jack (3.5mm). Common with headphones on portable devices like iPods.

It means stereo line out.

I stand corrected. 3 non connected circle segments indicates wireless, and it doesn't have an arrow. The sign is indeed audio out. Computer Basics - TechHelp

Thanks for the replies. I confirmed it is an audio out jack. That is what I suspected at first, but didn't think it was for audio, simply because on the side of the computer, literally an inch or two from that audio jack is a headphone jack (with headphone symbol). So that begs the question, is there any difference between the headphone jack and audio out jack? I tried connecting my stereo to both and can't tell any difference.

I think the difference would be the impedance.

Plugging some headphones into the headphone jack will probably automatically kill the sound to the stereo jack and any other output.

external speakers vs head phones with a mic so that you don't reverb back during webinars and conferences calls
