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.

    I am having the exact same issue as Mandy and Stephanie.

    Windows Audio Service has randomly gone off. I try to turn it on, and I get the same error "the endpoint is a duplicate."

    And just like Mandy, when I try to run sfc /scannow, the cursor just moves down one line and nothing happens.

    Any help would be appreciated. Everything was working fine until last night.... which is confusing since I haven't done anything to the PC.

    I am also having this problem with the audio. I tried everything you have suggested (checking the dependencies, running the SFC) and nothing is working. 

    Everything was working fine until Saturday night when i turned on my computer to receive no sound. 

    Is there anything else that I can do?

    Would buying an external sound card help?

    Wow! I'm having the same issue as everyone else, I haven't installed anything recently, it just happened. 

    I've tried all the dependencies and get the endpoint is a duplicate message. Deleted drivers and nothing.

    When I attempt to run the sfc /scannow the cursor goes to the next line but nothing happens.
