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
