    Hi,
    My laptop's sound isn't working, and when I mouse over the speaker icon in the corner there's a red X with the message "No Audio Output Device Installed." I've looked on other forums for the solution and here's what I've tried so far:

    -I've been told to disable and enable the sound device in Device Manager, but there's nothing under "Sound Video and Game Controllers"

    -I've tried to reinstall the audio drivers (Realtek HD Audio and Conextant HD Audio). The Realtek driver says it installed correctly, but it still doesn't show up in device manager or anywhere else and the "No Audio Output" message still persists. The Conextant driver gives me the error message "Cannot Find Device" when trying to install it, but I've noticed something weird: I can see a Conextant HD Audio thing under "Add or Remove Programs".

    -Windows Audio is running under Administrator Tools, I've checked.

    -I've done a system restore back to factory settings and it still doesn't work.

    My laptop is a Hp Pavilion dv6700z with Windows Vista Service Pack 1. I think a windows update might have screwed it up; I can hear a popping noise when plugging in my earbuds and I can hear the error beeps under system setup, so the speakers themselves work. Can somebody please help me out? :confused:

    I'm still thinking drivers, are you sure you got the right ones?

    Also, do you have a Recovery CD or Recovery Partition?

    I'm almost 100% sure that those were the right drivers, and I do not have the Recovery CD or Recovery Partition; I restored it using the built-in recovery software. Do you think it's my sound card itself that's causing the problem?

    Meaning you did a System Recovery?

    If that's the case, it may be a hardware issue and not a software one.

    Especially after installing the latest drivers.
