Ok go into the control panelsystem properties and open the "Device Manager" then go to "Sound Video & Game controllers" section and highlight your sound card by clicking on it once and then hit "delete" on your keyboard or "right click" on it and choose “Uninstall” from the drop down menu and when it ask if your sure you want to remove this device ? choose “Yes” and when the uninstall is complete then reboot your computer and the sound card should reinstall itself

If it fails the install due to not being able to find the install files then you will need to either tell it where the files are located or if you do not know then you will need to go to the Dell website and download the driver and install it .. But either way you will need to uninstall and reinstall the driver to get it to work again..

Testimonial: "Thank YOU thank YOU! this was driving me nuts, you led me to the right place, a just had to do a few extra things (download) and it's fixed! I was on the verge of destroying my laptop and was getting really frustrated. the only noise it would make is the annoying beep from pop-up windows. But now i can actually listen to music! Thanks again. Shannon"

    NOTE: if you do not see your sound card listed in the "Sound Video & Game controllers" section then look for a section called "other devices" and there it might say "multimedia controller" and probably have a yellow mark on it... that is your sound card..

    Just follow same instructions above..

    If you can not find it at all anywhere in the device manager then it is probably disabled in the bios and you will need to hit the "F2" at boot up time and re-enable it..

    Hope this info helps

How do you fix the sound

Assuming youve checked every volume slider there is (the one in whatever program your using, the one on the bottom right corner of the screen by the clock, and the master volume.....
Thab go to your start button on the bottom left of the screen (where you normally access all your programs), there should be a little "search bar" on the bottom of that list. Type on "device manager", scroll down the list and locate your speakers, right click and than go to properties. First try "update driver", if that doesn't work than click "Uninstaller driver" and restart your computer. That should do it.

My son's Leapster Explorer suddenly has no sound. If you hit the increase sound button, nothing happens. If you hit the decrease button you see the volume bar on the bottom of the page. Do you know...

I had same problem, just fixed it by a little hack. The volume up switch is broken.
1. Remove accessory door on bottom. 2. Remove all screws on back. 3. Open back cover.
Looking at the exposed board, there are 2 volume switches (back to back). Directly next the switches are four contacts: the upper 2 are for volume down, the lower 2 are for volume up.
4. Place the battery pack on the board and hold it down. 5. Press the power button to turn on the unit. 6. Use a small wire to jump the volume up contacts multiple times to change the volume to maximum (or desired level). 7. (Optional) Remove the volume buttons and throw away the rubber cushions to prevent the volume from changing. 8. Replace everything back in place.

My acer netbook is stuck on mute

if the little x over the volume bar is still stuck after moving it up you may have to hit the function key (fn) on your laptop and hit one of the F1-F12 KEYS that look like a mute or volume symbol also there should be a mute button on the laptop itself. if all that fails. go to (xp) right click on my computer -device manager-and see if you have a red or yellow x over your sound sound devices (win vista or 7) go to computer, sys prop on the top then device manager. if you see any of htose yellow or red warnings you will need to re-download the audio drivers from acer website Let me know if this helped.

No sound when computer is being shut down or playing music on windows media player. button next to power button not lite up. push mute button back off still cannot get a sound.

Check the volume controls and sound properties. Make sure that the master volume ins not in "MUTE".

Double-click the speaker icon on your tool bar. The volume controls will appear.

Check the Sound properties:

Right-click the speaker icon > Adjust Audio Properties:
Audio tab > make sure to select the right sound device.

Thank you and good luck!

Acer speaker?

There are two possible problems here. (1). The volume control on your monitor is turned down. With the button on the front of your monitor, find the menu/option button, and look for volume control (2) The volume coming out of your computer is low. Double click on the speaker at the bottom right of your screen, located on the start bar. Use the sliders to change the volume. This should fixya up.

Good Luck!
