    what is this Sound Research Corp. - Extension - 15.85.13.5816 ??


    hi so what is this Sound Research Corp. - Extension - 15.85.13.5816 windows update offers me this every day and it fails to install, i have Realtek audio but my suspicions are maybe i need this as well, funny thing is this is not listed on my HP laptop support page. but maybe this is the very reason why i don't have any way to change sample and bit depth in my audio area. maybe because i need this , windows is calling it a extension.

    Re-install your sound drivers from HP support. Several are given, that is for you to sort out.

    SRS components are in a lot sound drivers including Realtek.

    Then the update should either go away or install. Check diagnostic data has been sent with the Diagnostic Data Viewer app.

    yes but the drivers on the support page will not install get error not supported on this version of windows. HP is trying to get that fixed as soon as possible.

    what is the hardware ID number of the Realtek High Definition Audio device on your HP laptop, Tonyb?
    use the below site on getting the hardware ID of a device in Device Manager:

    @erpster4 here you go HDAUDIO\FUNC_01&VEN_10EC&DEV_0295&SUBSYS_103C8615&REV_1000
    HDAUDIO\FUNC_01&VEN_10EC&DEV_0295&SUBSYS_103C8615

    not sure if that will help i have updated Realtek inside device manager but it does not bring this one back, i think it got lost when windows updated to vr 2004 and deleted the old stuff from laptop manufacture, who has not released updated drivers. but there has to be a way to install it. as windows update is offering it to me it just fails to install.
