Some of you know I'm a tax guy so I've been buried up to my eyeballs and haven't had time to troubleshoot this. This morning I have a few minutes so I decided to go into Control Panel and see what I can find. What I found was a Realtek HD Audio Manager which I've never opened before. In there what do I see? The volume output is up full like it should be but it's MUTED!! Now the sound is back and the red light on the back of the PC is on so muting turns that off.

How did I miss that? I went back in and muted it again and then checked the icon in the taskbar. I'm pretty sure in other systems if it's muted there's a red X through the icon but now there isn't. I have to hover the mouse over it and a little blurb pops up saying Realtek HD Audio Output 100% Muted but no obvious X. You have to hover the mouse over it before you see that. Then I unmuted it again and figured out how to mute it from the taskbar icon and it's not a simple thing to do by mistake. You right click the icon, the little menu pops up and then you have to click Open Volume Mixer, then the click the speaker icon at the bottom of the volume slider in order to mute it.

In my OP I wrote the system was fine when I turned it off and went to bed and in the morning I turned it on and no sound and that's true so how did it mute itself? I would have had to do all that to deliberately mute it before I went to bed and I don't think I've ever muted the audio from any of my machines. Why would I do that? I go through a lot of effort to get my sound set up.

The good news is I don't have a problem except losing my mind...Jeesh
