Click Start, then type "services.msc" in the search line, press "Enter". When the Services window loads, scroll down to the "Windows Audio" service listing and double click on it. When that loads, click on the "Start" button in the "Service Status" section and wait for the service to start. Once that's done, (or if the service happens to be running at this time), in the "Startup Type" line, use the drop-down arrow to choose "Automatic". Click on Apply, then OK.
Hope this helps.
After an automatic update got an error message upon next start-up saying "Failed to connect to a window service". "Audio service is not running". Sometime boots up normally, but usually get this error message and Speaker Icon in tray has red X. Don't know who sent automatic update, but probably MS or could be Norton. What can I do to correct problem?
