Original Title: Windows 8 - No Sound

HP ProBook 6455b Windows 8 

Hello, the sound on my laptop stopped working suddenly, never had any issues before. Looked into services.mcs and see that windows audio service is stopped. When I try to start it I get a dialog box stating 'Error code 0x800706cc: The endpoint is a duplicate'. There's also a red x over the sound icon on the icon tray. Checked for drivers, all working properly and updated, so it says.. Can anyone please help :(

Thank you.

I have found the problem. You probably all have AVG 2014 as your antivirus. Somehow it identified Windows audio files as a virus and settle them on quarantaine. Go to AVG>>Virus Vault and restore the files. Answer yes to all replacements.

    What if you deleted the virus vault when uninstalling AVG before restoring the files?

    Hi,

    Sorry for the delayed response.

    I suggest you to follow the methods below and check if that helps.

    Disable anti-virus. 

    When you disable Antivirus:

    Important Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable your antivirus software. If you have to temporarily disable it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

    For most Antivirus programs, there is an icon next to the clock in the task bar, you should be able to right click the icon and either be able to disable it from there or you can go into the options and disable it.

    Note: If the issue still persists, you can turn on your Antivirus program later.

    Please uninstall and re-installthe audio driver and check.

    Please follow the steps below: 

    1. Press Windows key + R key, type devmgmt.mscand click Ok.
    2. Expand the audio driver, right click and uninstall the driver.

    After uninstalling the audio driver, please reinstall itfrom the manufacturer website and check if that helps.

    Do reply to us with the status of the issue so that we can help you further.
