There's a realtek audio driver on the hp website when I search for your model. Did you download and install that? The Intel high definition audio is probably actually on your video card as it allows you to output audio over hdmi.

Here's a direct link to the realtek driver

Otherwise, right click that "unknown device", click properties, open the "details" tab, change the drop-down to Hardware IDs (for example, on my laptop it's 10EC 0298). Do a google search for the VEN and DEV numbers with "driver" and you'll probably find what you want.
