    HP400 sound from internal speaker and rear jacks but not front jacks


    Hi-
    I can not get sound from my front jacks but I get sound through the internal speaker. If the rear jacks are enabled then they will work.

    Device manager shows: 2 high definition audio devices (not realtek). One for the rear jacks and the other for ATPI Inernal ATPI jack. No playback device listed for the front jacks.

    I tried uninstalling and reinstalling the devices but the front jacks wont install

    Any suggestions would be appreciated! Thanks!

    High Definition Audio Drivers are only the generic, basic function, Windows installed sound drivers. They are not the full feature drivers that the hardware drivers provide. Check HP for a correct sound driver, if available.

    ATPI (ATAPI) suggests this is an old Windows XP PC that was upgraded. There may not be any better drivers than the generic ones you have now.

    Also check the front panel audio connection to the motherboard (reseat the connector).

    Thanks for the advice. Should I also try to install the realtek driver I keep hearing about or stick with HP?

    Only install Realtek if that is what the sound hardware is. If you have some other hardware, such as Conexant the Realtek drivers are not applicable.

    The HP site should detail what you have.

    The site gave realtek as an option. I installed the driver (simple) and it detected the front jacks!
    Thanks!
