Computer Not Detecting Audio Output Devices?

I recently updated my computer from Windows XP to Windows Vista Ultimate. The problem that I have is that when I hooked up all the wires even the speakers, it said that no audio output device is installed. Can someone help me?

This can be tricky without being at the PC but I'll try to give you some paths to solve your problem.

First thing to look at is your "Devise Manager" (click Start - Control Panel - Devise Manager). In your Devise Manager there will be a listing called "Sound, video and game controllers" and it will have a + to the left of it. Click on the + to get it to expand. In the expansion you should see your sound card llisted.

If you see no sound card you need to attempt to install it. If there is a sound card listed make sure it has no red or yellow symbol on it signifying it isn't working. If it does you have to click on the symbol or the sound card and see if Windows will tell you why your sound card is giving it heartburn. If there is no symbol, right click on the sound card and select properties. The box that pops up has an area covering the bottom half that should tell you if it is having problems.


Come to think of it this is probably the best way to find out what any symbols mean too. See the image I uploaded.

If everything checks out here it is either the connection TO the sound card ( I had trouble with my PC sound once and somehow the speaker plug got partially pulled out, nothing worked). Or the wires into your speakers, this could be an issue especially if you have a box that all your speakers plug into and that box plugs into your PC. Basically check all your connections it the best advise.

One way you can check to find out if it is your speakers is to plug another speaker or a headset into the port on the sound card.

And THAT brings up another thing to double check, make sure you have your speakers in the right port on the sound card. If they are plugged into the sound IN port then there is nothing in the sound OUT port and you will get errors from windows. Good luck

I have a problem with my sound every time I reboot the computer (thankfully I don't have to do that often). I discovered, however, that if I scroll down to the icon with the yellow exclamation mark on it and right click and disable it, then enable it, my sound works as normal.


Path: Start->Control Panel->Performance and Maintenance->System->Hardware->Device Manager; scroll down
That is the route for XP; should think Vista has similar path.
If this doesn't work for you then you may have to install again as Suntydt has said.
Good luck!
