This is an audio codec: the chip that turns digital sound into the signal for speakers, headphones and microphones. It sits on the High Definition Audio bus of the chipset or the graphics card, so its hardware ID starts with HDAUDIO, not PCI. In Device Manager it is listed under Sound, video and game controllers, as "High Definition Audio Device" when Windows uses its own generic driver.
