need sound software

hi well i have no sound on counterstrike and their support site had steps that somehow lead me to uninstall my realtek sound driver and now all i get is a beeping sound and no sound works. i went on the realtek site and downloaded the sound driver software on the site for vista but after installing it it still doesnt work instead i get no beeping sound actually i get no sound at all.
the computer i use is an acer aspire 5570 laptop 32 bit with windows vista.
does anyone have any idea how to fix the sound and also a way to fix the sound on counterstrike also, any help would be great thanks
im guesing i need the certain version that i unistalled before
does anyone know where i can get it
please help asap , everything stinks without sound

Try this link: http://support.acer-euro.com/drivers/notebook/as_5570.html
In the middle of the page you'll see a Vista section and a drop down box for Drivers & Utilities. Click the downward-pointing arrow and select the Audio driver. Download it and re-install it. If that still doesn't work, check your BIOS and be certain that the audio is enabled. If it is and you still have no sound, then something must be turned down or turned off, or something is muted. Did you have sound before and then it stopped working? Was the sound OK on everything except for CounterStrike?

yeah i had sound before and when i accidently unistalled my sound software when i foolowed the steps on the counterstrike support page no sound works,
sound was good on everything cept for counterstrike but now it doesnt work at all

 

the sound still doesnt work even after i install it

 

i get location 0 when i go to the sound menu on device manager
any ideas?

 

I'm not sure I know what you're talking about. Maybe you could post a screen shot of the device manager? Is there yellow question marks or exclamation points in the device manager? Have you gone to Add/Remove Programs and if the sound driver is listed, have you removed it, rebooted, then reloaded it from the link I posted above?

please reply asap i cant last another day without sound lol

 

there is absoultely no sound with or without headset, the only thing i did is go to
"drivers" which is right next to "general" on the screen and clicked unistall and then the sounds gone.
i tried reinstalling the sound software and after reinstalling it it still gives me no sound

 

Can you 'roll back' using system restore to a date before all this started?
