I don't have any sound and there is a red x over my speaker and when I put my cursor over it it says No Audio Output Device is Installed. When I look under the "Sound" box in the control panel, I do not have any sound card information. Please send any suggestions you may have. I am not techy, so please explain as simply as possible. Thank you! Laptop, 2 years old. windows Vista

Make sure you have speakers plugged in to the "Green" audio out socket. you can use a set of earphones if you have to. You then need to go into the control panel and set the Default audio device. Unless the device has a little yellow or red mark on it in the Device Manager. in which case you have more than likely got a failed audio chip. A PCI sound card will give sound output if the rest of the Motherboard is good.

The USB port is damaged, or missing the driver for that port, check device manager.

To get "surround" sound, when you face the computer, you will have:
* 2 front speakers, one immediately on each side of the computer
* 2 side speakers, one on each side of your head
* 2 rear speakers, one behind each side of your head

Thus, when the sound is of a jet-plane coming towards your face,
you'll first hear the sound in the front speakers,
then in the side speakers,
and finally in the rear speakers,
to produce a sound-effect of the jet passing over your head, and going "behind" you.

Usually, for "front" speakers, one speaker connects to the other speaker, and the second speaker connects to the "FRONT-audio-output" connector on your sound-card.

For side speakers, one speaker will connect to the LEFT-side-audio-output port,
and one speaker will connect to the RIGHT-side-audio-output port.

For rear speakers, one speaker will connect to the LEFT-rear-audio-output port,
and one speaker will connect to the RIGHT-rear-audio-output port.

Hi there,
A TV without sound is awful. So let's take some steps to see if we can get it up and running.
1) Check your input cables - if you're trying to watch something through another device (cable box/satellite box/dvd player ETC) make sure that the cables coming from it are inserted correctly into the TV. If the device has it's own seperate sound output (VOL controls) be sure they are turned at least midway UP.
2) Check the settings on your TV - Sometimes TV's have a setting where you can select audio output (speakers, 2.1 5.1, stereo, etc etc) Make sure you have it set to output sound to it's own speakers and adjust the volume to an audible level.
3) Check the audio OUTput on the TV itself - Connect the white and red (or in some cases black and red) RCA jacks to the audio input on a stereo receiver. See if sound comes out. If this is the case, you have either selected the wrong output on your TV's settings, or your Tv's speakers are dead.

Hope this helps you solve your issue!

Hi tamjidzaee ,

Please follow the below steps to solve the problem that you have mentioned :-

1. Check if the sound driver has been installed in your system, you can check this by going in the control panel's sound and audio devices option , if you find all options disabled and it reads no playback devices and no recording devices, then you have no sound driver installed. Therefore in this case you would require to install your sound driver using your motherboard cd.
2. If you see your sound driver is installed in the audio options of the control panel and you also see the sound driver's name , then you need to check the volume in the volume settings to check if it has not been muted accidentally , if it has been muted , then please un mute it and things should work fine.
3. A good idea would be use a headset and plug it into your motherboard in the slot where the speakers output is received , mostly the green round slot.
4. If you have a front head phone option then you can try using it as well, if the headphone or headset works fine, then we are sure about two , things that the driver is installed successfully and there is a sound output from the audio output slots.
5. Now, when you have checked the sound via headsets then you need to make sure that you are connecting your speakers in the green slot or the same slot which is working for headsets, remember headsets can be used to check the output in the back panel of your cabinet as well as front panel of your cabinet.
6. Also check if there is any fuse in your speaker which has blown up so that you can replace it and it would start working, check the power cables and confirm they are not properly connected.

If the speakers work fine , then it's all ok , but if they don't you need to replace the speakers by checking them with your friend's pc or any other audio output device.
Hope his helps.

You most likely have no drivers or corrupted drivers installed for your sound card. You need to visit the Samsung UK support page that I've linked for you here: http://www.samsung.com/uk/support/detail/supportPrdDetail.do?menu=SP01&prd_ia_cd=1402&prd_mdl_cd=NP-R60F002/SUK&prd_mdl_name=NP-R60&srchword=NP-R60F002/SUK

1. Click on Driver.
2. Scroll down and look for the drivers that match your operating system. If you Windows 7, then choose a Windows Vista driver.
3. Click on the Zip icon on the far right in the Sound (Audio) row to download the driver.
4. Open up the downloaded Zip file and extract to a folder on the desktop.
5. Open up the extracted folder and double click Setup to begin driver installation.
6. Wait for driver and software to install and then restart computer if prompted.

Good luck, please post back to this solution if you have any difficulties, and thanks for using FixYa.

1. • 1 Make sure that your computer and speakers are plugged in, have power and are turned on. If the speakers are plugged in but don't appear to have any power, plug them into a different outlet. Some speakers are self powered and use a USB cable to supply power. Make sure that the USB cable of your speakers is connected securely to the USB port of your computer.
     
   • 2 Retest the sound. If you still don't have any sound, make sure the cable connecting the speakers to the computer (known as a 1/8-inch TRS cable) is plugged into the green audio output jack on the PC.
     
   • 3 If you're using self-powered USB speakers, remove the USB cable and plug it into a different USB port. If you're using outlet-powered speakers and have a working set handy, replace the suspected non-working speakers with the working pair to test.
     
   • 4 Navigate to the Microsoft Fix It troubleshooter (windows.Microsoft.com/en-US/windows/help/no-sound-in-windows) to automatically detect and fix sound playback or hardware problems. If that doesn't work, proceed with the next step.
     
   • 5 If you have an add-on sound card and none of the hardware or software fixes helps, you may have to replace the sound card. If you use on-board sound, it will probably pay to purchase an inexpensive sound card rather than a new motherboard. Check the system BIOS to determine whether you have inadvertently disabled your on-board sound.
     
   • 6 Navigate to the "Start" menu and select the "Control Panel" and "Sounds and Audio Devices." Then click the "Volume" tab. If everything is grayed out, proceed to Step 7. If the "Mute" box is checked, uncheck it. In "Device Volume," make sure that your volume level is set to a comfortable volume level for your speakers.
     
   • 7 Click the "Sounds" tab. Under "Sound Scheme," determine whether "No Sounds" is selected. If it is, click "Sound Schemes." A drop-down list will appear. Select "Windows Default" as the scheme. To test your sound now, click on a sound listed below the "Program Events" window. The sounds will be indicated by a small "Speaker" icon located next to them. Left-click the sound once, then click the "Play" button. If you still don't hear sound, proceed with the next step.
     
   • 8 Click the "Audio" tab. Under the "Sound Playback" option, make sure your sound card is selected as the default playback device. Usually, only one device appears here, unless you have multiple playback devices installed.
     
   • 9 If everything is grayed out, you either do not have a playback device installed or your drivers are corrupted and need to be replaced. Drivers help hardware and software function together. Fix this by reinstalling the appropriate drivers. Do this by navigating to the "Start" menu and right-clicking "Computer." Then select "Properties" from the drop-down menu. Click the "Hardware" tab and then click the "Device Manager" button. The Device Manager will open.
     
   • 10 Look for either a red X or a yellow question mark listed under "Sound, Video, and Game Controllers." If a red X appears, right-click the device with the X and select "Enable" from the pop-up menu. Test your sound at this point. If a yellow question mark appears, right-click the device, click "Properties" from the pop-up menu, and then click the "Driver" tab on the window that appears. Next, click the "Roll Back Driver" button to roll back to the previous drivers that were functioning correctly. Restart your computer when prompted.
     
   • 11 As a last resort, you can uninstall and reinstall the device. To do this, right-click the device and select "Uninstall" from the pop-up menu. Restart your computer. Windows will automatically detect and install your audio device upon boot-up. If you still don't hear any sound from your computer speakers, contact a qualified computer technician.
     

go to Acer site and click on support enter your serial number on bottom of laptop and download sound drivers hope this works...

Go to Control Panel - System - Device Manager - Sound, video controllers and uninstall the driver. Restart your laptop and reinstall the sound card driver. Good luck.
