well first after turning the computer on, immediately press F10....go to security and check if the audio is turned on (not invisible) if it is go to pci devices and check there if the sound is enabeled, don t forget to press F10 to accept values and reboot the computer goodluck
The most likely causes for this is:
External Speakers not turned on.
Turn them on...
Driver for the sound device isn't installed:
If you see the little speaker icon down the bottom right hand corner of your screen (near the clock), your sound card device driver is working well.
If it is not visable, the sound card device driver may or may not be working.
Go into the start button, select settings (if available), then control panel, Sounds and Audio Devices.
Select the Audio tab
Ensure that you have a 'default device' set.
If you get any errors when going into the sound and audio devices tab stating that you have no audio devices installed, then its most likely a driver issue.
In this case, refer to your local computer shop to have the audio drivers installed.
Driver for the keyboard sound function not installed or not running.
Reboot then test it.
Reinstall the driver, test it.
Go to Add/Remove Programs and uninstall the software related to your soundcard.
Go to Device Manager and remove the sound card it is the device that has an exclamation point or question mark.
Turn off your PC and remove the Card. Then turn it back on again and enter the BIOS setup and disable the built in sound card of your motherboard then press F10 and save the changes.
Restart your computer and verify that windows is not going to scan for missing devices. Check the Device Manager again and look for any devices that has an exclamation point or question mark. If there is none. Turn off your computer put the sound card back in and turn it on again. Put in the CD Driver but exit on the autorun let windows detect the card automatically and wait for it to ask for the location of the drivers. Point or browse to the driver location and let the installation finish and click on ok. Your PC may ask for another restart do that turn on your speaker and listen for the boot up sound if your hear it then your card is now working.
window media playar cannot play the file because there is problem with your sound device . there may not be a sound dvice .theremay not be a sound device installed on my compter it may be in use by another program or it may not be functioning properly
1. Are your speakers turned on and plugged into the correct jack on your sound card?
2. Is your sound card recognized by your OS? In Windows, press the Windows Key+Pause/Break to bring up the System Properties page. CLICK on the Hardware tab, then Device Manager. Is there a yellow exclamation point under the "Sound, video and game controllers" subheading? If so, you will need to either install/reinstall the sound card's driver or resolve a device conflict. Walk through the options on the device's Properties page.
3. If your speakers are on and your sound card is working properly (as reported by Device Manager), it could simply be that your sound is muted. Open the Control panel (Start>Control Panel) Open the "Sounds and Multimedia" icon. Verify the "Show volume control on the taskbar" checkbox is checked. If this option is not available or is grayed out, see below. If you were able to check this box, click ok and close out of this window and the Control Panel. Double-click the sound icon in the systray and verify that all the sound volumes are mid-way or higher.
4. If Windows thinks your Sound card is working properly, your speakers are on and turned up and Windows' software volume control is turned up, go back to Device Manager and Highlight your Sound Card. Press the Delete key on your keyboard and confirm that you do indeed want to remove this device.
Reboot. If your Sound card is functional, Windows will redetect it and offer to install the drivers for it. You may need your original Windows CD to complete this step.
your speaker is NOT a device that the computer can detect. You got a bad sound device problem. Check your motherboard's site for support (for built-in sound card). You might need to reinstall the sound card drivers. Try to check in the "Device manager". You must have the sound device installed before sound can be heard from the speakers :-)
If you have windows XP check : control panel / Sound speech and audio devices / Sound and audio devices. Then check that the volume cursor can be moved and that the device is not muted. If this doesnt work remove the sound card from device manager, and install it back using drivers from your recovery disk or download them from Toshiba website.
