    Have you gone to the "Control Panel" and then check the "default playback device" under the "Sounds" icon? The laptop has HDMI and maybe that has set itself as the default device with the headphone jack being the default communications device.

    the default device is "speakers and headphones IDT High Definition Audio CODEC"
    right under that there's another device "independent headphones IDT High Definition Audio CODEC"

    looks about right to me.....

    Have you tried to uninstall the drivers from Programs & Features and then reinstall them again?

    Also make sure you have you Service Pack 1 installed for Windows 7.

    And HP has a BIOS update that improves the fan control for that laptop, you should update it to prevent the massive failures that plagued so many previous HP laptop models a few years ago.

    If the sound works at all, you don't have a driver issue. Open Control Panel and verify that your audio output is set to your speakers, and you have the right configuration selected, i.e. if you have stereo speakers, don't try to run Dolby 7.1 audio. You can test various configurations until you find one that works. With some soundchips, you may have potential conflicts with the native utility, so make sure that port assignments are correct for the physical device connections.
