Vista - No sound after an update.

So I just updated Vista on my machine, and after it finished updating, and restarting, my sound was gone.
And every time I try to turn up the volume it says "No Audio Output Device Is Installed".
But it was working before the update. D=
HELP.

PC: HP Pavilion dv 6000 (GM006UA#ABL)
Other bits of information I also don't understand can be found here. I have no idea what that means, but it might be handy information.

can i start by asking, did you use windows update

also, did you install vista SP1 (Service pack 1) just before this problem occured

if you used windows update, open it and click "view installed updates" (top left of the windows update window)

reply to this message and list with all the updates you installed on the same day your problem started to occurr and me/another member will do some digging to see what might have caused the problem...

untill we know this information we won't be able to help you further.

i will keep an eye out for your reply........

This problem was all ready solved.

Uninstall the drivers & then download & install the latest from the manufacturers website.

perform a system restore and the sound will be back.

Parziale already has the problem fixed by downloading the drivers and installing them from the other thread post.

hey,

i have the same problem as well i also updated it n after the sound was gone noting "no audio output device is installed" but mine is
HP Pavilion dv2000 (GA726EA#ABV)
what shall i do!! :S

Goto HP's website and download the audio drivers here is the link omom.

Conexant High-Definition Audio Driver*

This happened to me after upgrading from Home Basic to Home Premium.

I could get no sound for some time then some clever guy in the shop where I purchased my computrer upgraded my sound drivers from "SigmaTel Audio CODEC" to "SigmaTel High Definition Audio CODEC", obtaining some drivers from the internet somewhere, and it has since all worked fine since.
