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.
No Sound with error message 'Error code 0x800706cc: The endpoint is a duplicate'. Also a red x over the sound icon on the icon tray.

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.

2014-09-17T01:30:33+00:00 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.
