What is that HP symbol ?

Hi all, what is that HP symbol which is highlighted in yellow ?

And the second question is about middle highlighted area.
Is that configuration is for noise and echo cancellation ? So you could program that using AC97 interface right ?

And there are no connection to analog selection muxes from the control interface. Is these kind of mistakes are normal
in datasheets normally , which I need to assume that they are connected ?

And this chip is around 2.28$ in digi key. Any cheap AC'97 compatible devices ?
Any suggestions ? I don't need super features like high sampling rates, echo cancellation just need to digitize some sound and connect it to a linux SBC.
