Troubleshoot sound problems

	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. NoteIf 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. 2. Under Main Volume, move the slider up or down to raise or lower the volume. NoteSome mobile PCs have an external volume control on the outside of the case. If you're using a mobile PC, check the external volume control. • Make sure you don't have headphones 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. If these steps don’t solve the problem, check the information that came with your computer and speakers or go to the manufacturer's website.

	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 it 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.
