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.

2014-11-16T18:51:59+00:00 I had the same problem with the endpoing is a duplicate message. I didn't have the file to restore in AVG, and my system restore didn't help. I tried everything I could think of like uninstalling the drivers and uninstalling AVG. I found a program called Windows Repair from tweaking.com. I ran the diagnosis with most of the options checked. It took more than 8 hours to run them all, but it fixed the problem and now my audio is working again. Not sure if there what specific option fixed the problem.

2015-03-14T06:36:39+00:00 Thanks for this solution! I am almost certain this is what happened to me.
Except that my virus vault is empty and I am wondering if I accidentally removed the file permanently when prompted by AVG. Is there any way to fix this easily?
Thanks.
