Solved So pissed. No sound after automatic update.

First,... why can't I install and run 8.1?!?!? It install but I run into an error when the computer tries to boot. I have this problem with my desktop and my laptop. Windows won't stop asking me to install it as well! So annoying!

Now,... automatic updates were installed as I shutdown. Now I have to audio! Can't figure out why. I don't really even have time to be figuring this out! I went into sound hardware whatever in the control panel. I hit the test button and I do hear the test tones. But when I go to listen to anything else I get nothing. This is the second time I am having to deal with this. The first time I had to actually yank the battery. After installing the battery again and starting the computer I got sound. Why? I dont know. Even the volume controls are acting weird. If I hit the volume up on the keyboard a few times and then hit the volume down,... on screen it will show the volume going up by 2 before going down. Also,... if I go to setting via the menu bar by the clock and see the volume icon with the value, if I hot the volume up and down and mute, the value wont change. Not until I close the menu bar and reopen it.

Please help me.

So after I shut my computer down, the sound started working. Everything started working fine. Whats going on here?
