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.

    Hey guys,

    So as you might have read I also accidentally deleted the files from the AVG vault. Well after lots of researching I finally found something that worked for me. Tweaking.com's Windows repair which can be found here:

    http://www.tweaking.com/content/page/windows\_repair\_all\_in\_one.html

    I also had downloaded Driver Booster 2.1 free here:  

    http://download.cnet.com/Driver-Booster-2/3000-18513\_4-75992725.html

    After downloading and running tweaking's windows repair, driver booster suggested updating some drivers. After that, the sound was back!!!! YEAH!!! Hope it works for you too!!!
