I have Toshiba Satellite U300. After using it for one year , i had to use the recovery DVD to re-install Vista. I got the red x on the volume control with the message: "No output device installed".
To solve this problem :
try to re-install the driver and manually point to the driver's file
If this doens't work, update the bios software, it takes 2 minutes.
this will make it work.
Hi! I just had the same thing happen to me today.... Go to your control panel, make sure it is on classic view. Click on device manager Scroll down to sound, video, and game controllers click on the plus to pull down the drop down menu right click on the driver that is there and click on uninstall. once it is uninstalled restart your computer and it will automatically reinstall itself...
hope this helps you! it did me!!!

This could be that the Onboard Sound Card is turn on in the Basic Input Output Settings, these control wich devices start and run when you computer is first turned on. Commonly known as the BIOS there very often is a setting in there for the sound to come from the onboard sound card or the one installed seperately. You must access this setting when you first sstart your computer, and switch it to disable onboard sound.
When you first connect the turntable, Windows XP (and Mac OSX) will often select the "USB Audio Codec" as the audio input and output for your entire system. Since your turntable does not have speakers, audio will not be heard from your programs until you tell Windows not to use the turntable as an output device. Here's how to change these settings so that your internal sound card will always be used for playback whether or not your ION TTUSB is connected via USB: For Windows:
On the bottom left of your screen, select the "Start" menu.
Select "Settings" then "Control Panel".
In the window that opens, select the "Sounds and Audio Devices" icon. (If you don't see a choice called "Sounds and Audio Devices," choose the "Switch to Classic View" option in the panel on the left of the window, and the "Sounds and Audio Devices" icon should become available in the list on the left.
Select the "Audio" Tab at the top of the "Sounds and Audio Devices" control panel window.
Under "Sound Playback," choose your internal sound card as the default device. This varies by computer but should not be set to "USB Audio Codec" or "Microsoft Sound Mapper".
Under "Sound Recording," select "USB Audio Codec" for your default device.
Check the box titled "Use only default devices".
Click "Apply"...then "OK".
Open your Hard Disk.
Open your "Applications" folder.
In the "Applications" folder, open the "Utilities" folder.
In the "Utilities" folder, open the "Audio MIDI Setup".
In the "Audio MIDI Setup" under Audio Devices, set:
"Default Input" to "USB Audio Codec"
"Default Output" to "Built In Audio"
"System Output" to "Built in Audio"
Now, all programs, including Audacity, will only use your internal sound card for audio output.
if you are having problems with your sound if your computer came with a motherboard disc the sound drivers could be on it click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers click start control panel sounds and audio,volume,advanced,speakers make sure you have selected the (((appropriate speakers))) also audio you will find 3 drop down lists make sure you have the correct settingsthere also click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can change your settings there you can also tick in the box place icon in taskbar if his does not fix the problem
have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) also you might check the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer hope this helps don
Bad News boy, Since you already checked the drivers and teh volume option. which makes it eaasy for us to identify the root cause of the problem.
So try these steps.
1. Check in sound and audio device properties in control pannel, if you have the correct audio device listed. also check if nothing is on mute in volume control.
2. if its not the correct one. i suggest remove the existing driver from add and remove program and then try reinstalling it.
3. If thats the correct one, then Check if the external speakers / head phones produce sound.
4. if yes, then everything is fine in the computer, Don not do anything as all the software is fine.
5. If no, then the internal speakers have gone bad, which is ver rare, but it may happen.
Consider replacing the internal speakers,
I am sure this will help you.
Best of Luck!

What type of computer is this?
If you are building this unit yourself, and your motherboard does not come with audio. Then you must purchase a Sound card. I think Soundblaster is a good choice...Try clicking on sys information and see if you system has Audio. if so then check and make sure you have plugged your speakers in too the right output port, look at the back of the computer its usually the green jack.
This happens because the video card has hdmi output. Since hdmi output can carry audio signals also, the audio driver gets disabled. Uninstall audio driver and video driver both, install the video driver, and then install audio driver. after installing the audio driver, in playback and recording devices choose choose the audio output device you purchased along with the computer. This should fix the issue.
1024 X 768 is the ideal setting for a 17" Monitor. Are you still getting sound output despite the error message? If no sound then your integrated sound card has failed, you will have to install anew one in the PCI Slot, otherwise forget about the warning & keep listening. You could try visiting the Official website to see if any driver updates have been released till date and refresh the drivers(sound) installation...............sodeep PS: Check your Floppy drive? If not working simply disconnect and likewise in the BIOS if REQUIRED.
windows key + R = open : devmgmt.msc Sounds, video and game controlers > (right click) Realtek high definition audio > update driver sofware > browse my computer for driver software > let me pick from a list...> double click on Realtek high definition audio > YES to update driver warning > AND SWEET SOUND IS AUDIBLE :D
