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 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?

    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.

    Dear MS team

    I am having the same issue as described here. I have tried each of Geethu's fixes, except for the audio driver download as the Acer website (Aspire V3 win 8 not yet 8.1) doesn't have one more recent than the unit I am using.  

    I am presently trying to run sfc / scannow in administrator mode but nothing is happening - the screen shot illustrated in Geethu's helpful response doesn't look like mine. All that is happening is that after hitting Enter, the cursor moves to the next line but simply continues flashing. 

    So now I have a problem which I don't even know can be fixed. 

    Please, can someone help?

    Mandy

    Hi Stephanie,

    Thank you for the reply.

    Did you check if the dependency services are started?

    I would suggest you to run System File Checker (SFC) scan and check if it helps.

    Use the System File Checker tool to repair missing or corrupted system files
