And, in all of a sudden, i have no sound at my hp laptop, right after I updated my windows vista. I tried the ''system restore'' solution, but it did not solve the problem. I cant even play the test sound, because I see the error message : ''failed to play test tone''.
My model number is dv7-2030eV and my product number is NQ560EA#B1A. My operating system is windows vista 32-bit.
Any help is appreciated. Thank you in andvance and Happy Holidays!
