No Audio Output Device is Installed

Problem
My sound icon has an x on it, when I highlight the icon with mouse it states No Audio Output Device is installed. I went to Device Manager it doesn't even show no sound device. I have installed drivers but it won't work because it needs a sound card, I believe it is realtek sound card not sure.
I also have the Acer 5100 Notebook, when I received the laptop the only CD they gave me was for Windows Vista Home Premium that is installed on my PC. Instructions stated to do a Back-up of all the programs and files on the PC before using it. I did that, so I have the back-up. If I run my back-up will it erase all my info on my pc? Will it restore my sound card?
I believe this all started when Windows Update did a update this month the end of July, everything updated except one update, and that was the New Vista Service Pkg 1. So, I didn't think anything of it, so it required me to restart my computer, and then when the pc was up and running again I didn't have a sound device, I didn't notice it right away until I tried to open windows email, it wouldn't open. I tried playing songs on my media player no sound. So, I tried to do another Window Update, hoping it would restore my sound card. But it stated I had all the updates except one which was New Vista Service Pkg 1.
Everytime I would try to update to that version it would stop in the middle of the update, and ask for the CD for Microsoft Word 2002, I couldn't find the CD, and the update failed. Window update wouldn't install the new version of vista. At first the Window Vista would not update to my pc until I removed XP version of Word 2002 from the Acer Laptop.
So, I decided to uninstall Word 2002, rebooted, then updated to the New Windows Vista Service Pkg 1. no problem updated ok. So, I restarted my pc thinking it would restore my sound card. No sound card. Tried to do another windows update. Stated No Updates are Available at this time.
I have been going to other forums alot more people are having the same problem. I went to Acer, and Realtek, no downloads for Sound Card, just driver, downloaded that, but still I don't have a sound card. I went to some sites, and they want you to pay them for downloading drivers, and sound cards. I'm not going to do that, so I guess I will contact Acer Support, and Realtek Support, and Defintely Microsoft Support.
This is ridiculous. Especially since there are many people having the same problem. It has to be a bug in the new microsoft windows vista service pkg. 1 update. my does not show the icon but when i got to control panel i see it there but when i clik it says no audio so i cant here any sound I bought a Toshiba(Model: Satellite U305-S5097) notebook last year. But sometimes the audio device does not work. It shows "no audio output device is installed" with a red cross at the corner, But sometimes, the sound comes back. It makes me mad. I tried all kinds of methods but did not work. When no sound, no "Sound, video and game controller" in Device Manager. Please someone who know the solution to help. Thanks!

  • ChezBezz98 Apr 19, 2009

    I have the same problem as you I'm afraid...On my sound icon it has a cross on it X. When I hover my mouse on it it says: i No Audio Output Is Installed. I press the left click button and it has a list saying: Playback Devices, Recording Devices and Sound. I tried to solve it but you need to install something, but what? When I done loads of defraging on my laptop, it was on MUTE. Was that why? Especially because I'm only 9 years old! I told my dad but he said it will get the audio sound soon. But it never did. I need to install something. I tried once but you needed to pay for it, so I didn't bother...Please, I need a solution. A FREE solution. Fast. :( Thank you.

If you are going to use your restore disks, the system will go back to the factroy settings, which means it will work in a way it worked when you purchased it. So as a result you should surely have your sound card working.
However any software or data which you loaded after purchasing will be lost as well.


Also before using the PC restore, you may also try the system restore.
System restore is a utility using which we can take the system back to a date when it was working fine. It will undo all the changes happened after the chosen date.

Steps for system Restore
Start>Programs>Accessories>System Tools>System Restore.
Than choose a date in the calender when you think that it was working fine.

Any software and programs installed after the chosen date will not be there. You should not loose your data as well.

I hope that i have answered your query.
All the best
Sammy

Here's what I did to solve the same problem with my computer:

1) From the start menu click control panel
2) In control panel, click Uninstall a program
3) In the programs and features window, select Sigma Tel Audio, and then click Uninstall
4) In the user Account Control dialog box, click continue
5) In the Confirm Uninstall dialog box, click ok
6) In the configuring Sigma Tel Audio Driver and Applications dialog box, click finish.
7) Restart the computer

When it turns back on Windows reinstalls it and your sound is back on!!

    I had the same problem, but fortunately I had set my restore point one day before the problem appeared, so when I restored my system to that point.... Everything set up fine and now I'm writing this listening music in the background :-)
    thanks to my brother, who set up that restore point ;-)

Logitech mouse problem


I assume there is no second mouse on the system and you are using keyboard commands. Try the following in the device manager..
  1. Press Control-Esc or press the Windows key on your keyboard to bring up the Start menu.
  2. Using the up arrow key, highlight "Settings."
  3. Right arrow key to "Control Panel" and press the enter key.
  4. Use the arrow keys to highlight the System icon and press the Enter key.
  5. Use the right arrow key to select the Device Manager tab. (For Windows XP/2000 , use the right arrow key select the "Hardware" tab. Now use the tab key, select the "Device Manager" button and press the enter key.)
  6. Use the "Tab" key to select the "Computer Icon" at the top of the list of device icons.
  7. Use the down arrow key to highlight the Mouse icon.
  8. Use the right arrow key to open the mouse icon and verify there is a mouse icon that states, "HID-compliant mouse," and another entry that states the name of your USB device.
  9. If there are any errors reported on these icons by exclamation points or red X's, highlight these icons using the arrow keys and "Tab" to the "Remove" button and press the enter key. (For Windows XP/2000 , highlight these icons using the arrow keys and then press Alt-A keys. From the "Action" menu, highlight "Uninstall" and press the enter key.) When the "Confirm Device Removal" box appears, press the enter key.
  10. Once these icons have been removed, use the Tab key to get to the "Refresh" button and allow Windows to re-detect the pointing device. (If u r using Windows XP/2000 , press the Alt-A keys. From the "Action" menu, select "Scan for hardware changes" and press the Enter key.)
  11. Use the arrow keys to open the Mouse icon again and verify that there are no errors reported.
  12. Power down the computer system and restart Windows.
