if some ppl still have this problem Try this: Control Panel / Administrative Tools / Services, then for both Windows Audio and Window Audio Endpoint Builder, under the Recovery tab, choice 3, Subsequent Failures, change the default from "Take no Action" to "Restart the Service." That will automatically restart the service if it fails more than twice. im using a razer headset so i have thoose drivers they took over the normal drivers from windows if you have the same thing dont touch the windows audio only the 1 you replaced it with like in my case razer surround audio service this worked for me on 2 computers i hope it helps for some1 else aswel Doesn't work for me. Only the trick with restarting HD Audio Device in Device manager works.

if not uninstall them and install again.
