Hi everyone!
I desperately need your help!
A week ago I bought a laptop (hp pavilion dv2530ea with Windows vista).
The first time I used it EVERYTHING worked fine! (including the sound)
After connecting it to the internet, downloading and installing the new updates the sound stopped working.
Although the device manager claims the device is working properly, it isn't
I've tried evrything but nothing works.
(I spent the last 3 days surfing the web and reading threads and I noticed that few people have a sound pbm but I didn't find the solution)

When I try to test the sound I get the message "Failed to play the test tone"
and when I try to play a file using wmp i get "wmp encountered a problem while playing the file..." and the error code is C00D11B1

Please need your help!!
I'm desperate.
Thanks

Sounds like an easy fix. If the device manager says its working fine and theres no yellow question or exclimation marks then just uninstall the drivers, turn the computer off and back on and let it install itself, check the device and if its not working right use the drivers and software CD that came with your laptop and just use those sound drivers. MS has never really been good with updating hardware drivers and stuff, atleast in my experience.

Thanks very much for your help. I tried uninstalling the drivers and then reinstalling but it didn't work. my laptop didn't come with any CD's - it says it includes a new system recovery feature that does not require CD's or DVD's. But it tells you how to burn your own recovery discs. Do you know if I will be able to install ONLY the drivers from the recovery CD? Or will it be like reformatting the whole computer?

I have the exact same problem, I updated my software and my laptop went silent. and everytime i hovered my mouse over the sound device icon at the bottom of the screen and it says "No audio output device installed " what does that mean ???? any solutions >

you need to find out if your audio is Realtek or Sigmatel

Uninstall the drivers and software from Programs and Features.
Download the latest HD Audio if Realtek or latest drivers from Sigmatel.

This should resolve the problem. MS put out a bad audio driver update.
This affected XP also.

You might try going to the control panel and device manager. Go to the sound card. Click on it. There is a tab for driver and there is an option to roll back to previous driver. This will load the original driver back for that device. It's worth a try before going to Realtek site. ( It's a bone for downloading drivers ).

You sir, are amazing. I freaked out and thought about this right as I read it from you. This works I recommend it to anyone who has this problem.

DAMN YOU WINDOWS!!!

MacLynn!

Thanks so much! You saved my laptop too. I thought my "very dear" laptop's sound broke. It was playing the songs or sound but not coming through the speakers.

Thanks again MacLynn and Google!!!!


Darn the updates!

Hello!

Exact problem I'm going through. And the suggested roll back to previous driver button is not clickable.

Anyone please HELP!!

Try going to the laptop makers website and downloading the drivers..
