Hello how to install my audio devices coz no have saund my speaker

hello jenz8860, try open device manager (run type devmgmt.msc), if u find question mark on your audio device then u need to install audio driver.
to install audio driver use motherboard driver, insert to CDROM, right click the audio device on device manager then update driver. choose recommended option then click next and follow the instruction. your audio device will automatically installed. if it success installed then u need to restart your PC.
if there is no problem in device manager, high possibility it's on hardware problem, try to see cable connection between speaker and PC (use back panel connection, don't use front panel audio, this to make sure the connection is good), if it's ok then mostly problem came from your speaker. try to use another speaker.
hope this useful, regards.

if you mean SOUND problems
if your computer came with a motherboard disc the sound drivers could be on it
you might have to uninstall then restart your computer then reinstall both the sound drivers and the sound card make sure you have both of these devices backed up to a disc before uninstalling
a yellow? question mark means you need to install/update driver to do this
right click to install driver also
click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers
click start control panel sounds and audio,volume,advanced,speakers select appropriate speakers also audio you will find 3 drop down lists make sure you have the correct settings there
also
click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can change your settings there you can also tick in the box place icon in taskbar
if his does not fix the problem

have you tried this control panel sounds and audio,volume,advanced,speakers select the appropriate speakers from the drop down list or navigate to the device manager scroll to system devices + to expand,system speaker right click properties then select use this device (enable) also you might check
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the sound card and the CPU central processing unit dust causes static to build up in a computer
hope this helps

Maybe your saund card doesn't work on windows 7... Which sound card do you use, or what motherboard do you use???

Speakers do not need any drivers!! Your sound card need drivers.

If your sound card is PCI, remove it and reinsert it to the PCI slot again and see whether your system detect the device and use the sound CD to install the drivers. (Change PCI slots if necessary and turn off the PC before changes the PCI sound card).

If your audio device is intergrated device, check the Bios to make sure the sound/audio is enable.

Note: Check the device manager first to see any audio device had been install properly.

you just click on this link and download Realtek.Zip. after download 1st you unzip the Realtek. And Install the driver and enjoy with sound. Sound Card Driver for LG K2 Express Dual

well it depends on what audio device installed on your computer coz other you can make an adjustment for 4 channel, 5 channel & 7 channel speakers including sub woofer and surrounds. try to check your setting or the best way is to unplug your front speaker and sub woofer. good luck!!!

pls insert your motherboard cd in you computer and reinstall sound diver and after restart your pc .......and all pins are proper connect in computer .........speaker is working ..........ok

You need to install the sound drivers for your PC. go to the manufacturers website, (ex.www.hp.com) and go to the support section, sometimes called downloads also. It will prompt you for your model of PC and what Operating System ( XP,Vista,etc..) and then it will list the drivers that are available. you should update anything in "DeviceManager" that has anything except the "+" sign beside it.
