I can't hear sound from my computer.

There are a few simple things to check first:

• Make sure your computer has a sound card.
  You must be logged on as an administrator to perform these steps.
  1. Open Device Manager by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager.‌  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
  2. Expand the Sound, video and game controllers category. If a sound card is listed, you have one installed. If no sound card is listed, You will need to install one. See Install or remove a sound card.

     Note

     • If you think you have a sound card installed but you don’t see it under the Sound, video and game controllers category, expand the Other devices category and check any devices listed there.
  3. If there is a yellow question mark next to the name of the sound card, there might be a problem. Right-click the name of the sound card, and then click Properties.
  4. Click the General tab, and then look in the Device status box to identify problems with the sound card.

• Make sure your speakers are plugged into a working power source and turned on.

• Make sure your speakers are correctly connected to the computer.
  On your speakers, find the cable that plugs into your computer. Make sure that the speaker cable is plugged into the speakers and the correct jack on the computer. For example, if the cable is a 1/8 inch cable, there should be a round jack for it on the back of the computer. If it is a universal serial bus (USB) cable, it will plug into any USB port on your computer.

• Make sure that the speaker volume is not muted or turned down too low.
  1. Open Volume Control by clicking the Start button , clicking Control Panel, clicking Hardware and Sound, and then, under Audio Devices and Sound, clicking Adjust system volume.

• Make sure your headphones are not plugged into the line out (headphone) jack of your sound card or computer (unless you want to be listening with headphones rather than speakers). When you plug in headphones, most computers automatically cut the sound to the speakers.

I have a sound card in my computer, but Windows doesn't recognize it.

For Windows to recognize your sound card, you must find and install a compatible driver for your sound card. Most sound cards require driver software to work properly. Be sure that you have installed any software discs that came with the device. If you don't have a disc or the software on the disc does not solve the problem, follow these steps:

1. Check if a driver for your sound card is available through Windows Update. For more information, see Install Windows updates.
2. If Windows Update does not find a driver for your sound card, visit the website of the sound card manufacturer to check if a driver is available. If one is available, download it. If not, contact the manufacturer.
3. Open Device Manager by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager.‌  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
4. In Device Manager, look for a sound card under Sound, video and game controllers and confirm that Windows does not recognize your card.
5. Close Device Manager.
6. Open Control Panel by clicking the Start button , and then clicking Control Panel.
7. In the Search box in Control Panel, type add hardware.
8. Click Install drivers for older devices with Add Hardware wizard.  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

I found a new driver for my sound card, but I'm not sure how to install it.

Windows Update can search for updated drivers and install them automatically, but if you already have a new driver you want to install, you can do this yourself. Out-of-date drivers can cause sound problems, so it is a good idea to install the latest driver for your sound card. Follow these steps:

1. Open Device Manager by clicking the Start button , clicking Control Panel, clicking System and Maintenance, and then clicking Device Manager.‌  If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
2. In Device Manager, locate your sound card under Sound, video and game controllers, and then double-click the device name.
3. Click the Driver tab, and then click Update Driver.

I'm having trouble installing my sound card and wonder if it is compatible with Windows Vista.

To find out if your hardware is compatible with Windows Vista, go to the Windows Vista Upgrade Advisor website. This website contains the information that used to be on the Windows Hardware Compatibility List.

I’m having trouble getting a portable music player, microphone, or other audio device to work with my computer.

You can use the line-in connection on your sound card to connect a portable music player, microphone, or other audio input device to your computer.

However, the line-in connection to your sound card is muted by default. This means that if you plug an audio device into this port, it will not produce any sound on your computer until you enable sound for the line-in connection.

Most sound cards have at least one line-out port to connect speakers and a line-in port to connect an audio input device

To enable sound for the line-in connection

1. Open Audio Devices and Sound Themes by clicking the Start button , clicking Control Panel, clicking Hardware and Sound, and then clicking Sound.
2. Click the Playback tab, click Speakers, and then click Properties.
3. Click the Levels tab, and then, under Line In, click the Mute button to enable sound for the line-in connection.

The line-in connection is muted by default

I've tried all the solutions here and still can't get my sound to work properly.

Some sound problems can't be solved by the solutions listed above. For example, problems can occur with specific models of hardware, such as a certain sound card, music player, or headset. It might help to check the Microsoft Knowledge Base (KB) to see if it contains any information about your sound hardware.

If you’re stuck, here are some Knowledge Base webpages to start with:

• USB speakers
• Sound cards
• Microphones

You can also check for support information from your hardware manufacturer. They might have information about problems with your specific model of computer or sound card:

• Dell support
• HP support
• Lenovo support

Common Keyboard Problems & Solutions

 

Hardware

• If keys stick or certain keys become unresponsive, dust and dirt are likely causes. Turn the keyboard upside down to try to release the dirt trapped inside. If that doesn't fix the problem, use compressed air to spray a jet of air between the keys, releasing any debris.
  

Software

• Keyboard layouts, set by the operating system, use different alphabets and accented letters for different languages. If you type a key and the wrong letter or symbol appears, your system may be using the wrong keyboard layout. Change the keyboard layout preferences back to your desired layout.
  

Settings

Laptop computers often have a "number lock" setting that turns a section of the keyboard into a numeric keypad. If some letters on your laptop keyboard produce numbers instead, check that you haven't turned on this setting by mistake. A keyboard shortcut usually controls it.



 For some reason your keyboard just stopped working, what can be the causes?

Solution

1. The most common problem when faced with a non-working keyboard is an improper connection. Try reconnecting your keyboard, restart your computer and see if that fixes it.

2. Turn off the system. Unplug the keyboard connect and inspect for any bent or broken pins. If the pins are bent, then it is possible to gently straighten them using the tip of a ball point pen or mechanical pencil. If the pins are broken, then replacement of the keyboard may be necessary.

3. Try updating the device driver. Visit the manufactures web site for the latest driver available for your keyboard make and model.

4. While at the manufactures web site. See if there are software patches or updates available for your keyboard. If there are, go ahead and install them as well as the updated driver.

5. If you are using a multi-media type keyboard, be sure to delete the software before installing any new drivers for this type of keyboard.

• Install the updated driver for the manufactures web site, then re-install the keyboard software.
• If any software updates or patches are available for your multi-media keyboard, install them at this time.
• Delete the keyboard software by using Add/Remove Programs (Start>> Control Panel>> Add/Remove Programs).
• If you receive a prompt asking if you would like to remove all shared files, answer "No to all". Then click OK.
