I tried to update me laptop system.

Anyhow, before i did the update. i had sound on my computer.

After the update, i saw that "x" over my sound icon.

I honestly didnt realize what it was until I didnt want to hear the Starbucks musci anymore. I needed a sound of my own. So I tried to play my music (which took me forever to rip).
And i received a message "No audio output device installed"

Anyhow, being that my sound was just working fine before, i used teh "Search" tool and keyed in "Audio"

I brought up several different things, but the main thing was an "audio setup" icon.

I double-clicked on the icon and presse a few "ok" and my audio device was reinstalled.

I hope this helps.
