TV Sound Randomly Quits Working (HP 873n)

    I posted an inquiry about this issue early last moth and was given the
    advice to reinstall all of my drivers and DVD codecs - which by the way
    didn't work. In monitoring this news group I learned that many people are
    experiencing the same issue.

    The other day, I was stumbling around HP's knowledge base and came across an
    article that linked a very similar problem to Norton Anti-virus 2003
    upgrades. Incidently, I upgraded my NAV to 2003 about a week before I
    upgraded MCE to 2004. I thought the problem was related to the MCE upgrade,
    however, I am now wondering if the problem might be related to the upgrade
    toNAV 2003. The article isn't a perfect match (i.e. it reference watching
    TV through WinDVD rather than MCE), but I thought it might be more than a

    A couple of nights ago, I completely disabled NAV 2003 and recorded about 5
    hours of TV shows. I didn't lose sound at all. This is a step forward as I
    lost sound at some point in almost every recording previously. I have not
    lost sound for two full days. Usually, I lose sound at least once a day.

    Has anyone else experiencing this problem recently upgraded to NAV2003? I
    would be curious to see if there is a pattern.

    BTW, I will put the text of the HP Knowledge Base article below:

    <-----------BEGIN HP KB ARTICLE-------------------------->
    HP Pavilion PCs - No sound with TV Tuner Card and Norton Antivirus 2003

    After installing Norton Antivirus 2003, PCs configured with the TV Tuner
    card lose sound after a few minutes when watching TV using InterVideo


    The workaround for this issue is to disable the Instant Messenger scanning
    feature in Norton Antivirus 2003. Follow the instructions below to disable
    Instant Messenger scanning:
    1.. On the Windows taskbar, click Start, Programs, Norton Antivirus,
    Norton Antivirus 2003. Norton Antivirus 2003 will open.

    2.. Select Options.

    3.. Click on Instant Messenger, located on the options menu on the left.

    4.. Uncheck all Instant Messenger clients, and click OK.

    5.. Reboot the system.

    NOTE: HP is working with Symantec to find a solution for this issue.

    Your message got me thinking - I also thought my loss of
    TV sound was related to the installation of MCE 2004. I
    realized that I had installed NAV just a few weeks
    before. I installed Corporate Edition, version
    7.60.926. I can't find any settings that speak to
    Messenger, although I'm sure it's doing similar things to
    the NAV code that you're working with. Any idea how I
    can change the messenger setting on the Corporate version
    of NAV?

    BTW - I've updated all of my drivers, etc. Nothing
    helps. I'll lose the audio from live TV somewhere
    between hours to days. The only way to recover is to

    I am not sure the corporate edition of NAV has the IM scanning capabilities
    that 2004 does. I checked both the client and the NAV server configuration
    tools and neither reference the IM stuff that my 2004 retail copy had.

    Incidently, I did lose sound again on the same afternoon that I posted my
    message, however, this time I picked up the phone and called HP for support.
    They had me reinstall drivers for several sound devices, however, the
    procedure they had me use was different than I trieed earlier. Here is what
    they had me do:

    1) Go to device manager
    2) Expand the "Sound, video and game controllers" section
    3) Right click on each device and if the right click menu for the device has
    an "uninstall" option, select it to uninstall the device and driver
    4) Repeat this for each device under that section
    5) Reboot

    When you reboot, the devices will be readded and configured automatically.
    After we did that, they had me run MSCONFIG and deselect any unnecessary
    items from the start up tab.

    Since doing the above procedure, I have not lost sound (Wednesday, Thursday,
    Friday, Saturday, Sunday and today). I would have expected to lose sound by
    now. I am cautiously optimistic about the future.....

    Give the above a try and let me know how it works.

    Thanks for the advice - I think it's fixed. I didn't
    bother to look at the startup files - I only unloaded the
    audio drivers. I suspect that you only need to reload
    the Emuzed drivers.
