No sound on computer


Exit all programs and then re-boot the computer first to see if the sound returns. If you hear the start up sound, things are probably working.

Here is a link to the Dell support page to investigate further:

Pls i can"t hear the


You just need to download the appropriate audio driver for your computer. Go to the Device Manager and install all missing drivers for "Unknown Devices". Either connect to the internet or use the driver disc which came with the motherboard of the computer.

For those who doesn't know how to access Device Manager, please follow the steps below.

For Windows XP:
Start -> Run -> Type devmgmt.msc (in the box) -> Right click Unknown device -> Properties -> Driver tab -> Update driver

For Windows Vista and Windows 7
Start -> Type devmgmt.msc (in the start search box) -> Right click Unknown device -> Properties -> Driver tab -> Update driver

Hope this helps.

No sound with Acer Aspire 4720z; have completed system restore, updated drivers, made sure that nothing is muted.....any suggestions?

Here is a suggestion : On desktop go to ::
my computer----mouse right click----properties----system----device management. There you can find symbols for all devices that are already installed on your system . Scroll down until you find the definition of your audio device software , for example , if your audio driver software is a realtek then right mouse click on it , then you'll find disable , just disable it and then uninstall the audio driver software ! After that you should restart your system . When system started again , install the software again , and restart the system once again . Now you should hear the operating system starting tone .. If you didn't hear the tone , then go to device management again and enable the audio device once again .
good luck . rate if useful please !

I have recently connected internet service at home but due to virus or something i cannot hear the sound on the computer anymore. i have selected service of 29.99 a month without a payable of $5 for virus....

First thing I would do is run a free virus scan from Trend Micro called House Call.. It takes a while but is quite thorough.. Once complete and you find and eradicate any viruses, then you can investigate the sound problem.. Normally, the first thing I suggest you verify is that your sound volume isn't set to Mute of very low.. You can check that by selecting the START button, then CONTROL PANEL, then SOUND and AUDIO Device tab.. once there..youhave a number of options to do,... first off.. check speaker volume and make sure they are set to at least the midpoint and the mute box isn't checked. If that doesn't work..then chose the hardware tab and scroll thru the list until you find your sound device..If you highlight it, then select properties.. it will tell you if the device is working properly.. You can also select the Driver tab and update the drivers or roll them back .. These are a few things to try.. I would strongly encourage you to protect yourself by installing an antivirus program... There are many available but it is wise to have one.. Good luck..and I hope this helps you get your system going again..

No sound

well, there are a number of things you can try.

1) test the speakers on another unit, see if they work. Make sure they are plugged in and a headphone is not plugged into the machine

2) make sure the mute is not on, and that the computers volume control is turned up (this can be found on the bottom right of the task bar)

3) check the device manager (find this through the control panel). Make sure the device is enabled and drivers are current.

4) replace the sound card.

It would be helpful to know the context of your situation. Did this happen all of the sudden? Do you hear anything at all through the speakers?

Did you have sound before?
If yes then follow this for xp:
Start/control panel/Sounds, Speech, & Audio Devices/Sound & Audio Devices. Is page greyed out? If yes then most likely its your sound card or on board sound, or your missing drivers.
If not greyed out go to "Sounds" tab, click on any "Program events" sound under Windows then click little black arrow next to browse on bottom right . Sound? If the arrow is greyed out then its the same; audio hardware device or audio driver.
If there is still no sound click on "Hardware" tab and first Sound,video and game controller then "properties". This will tell you under "Device status" if this device is working properly. Do this for each Sound, video ect.... selection in the list. I have found there are usually 6 listings. If not then you are most likely missing a sound driver.
