Updated windows XP to windows 7 but no sound

I upgraded my HP dv5000 laptop from Window Xp to Windows 7 but now the sound doesn't work at all. I tried to use SP35558 and Vista_Win7_R262 software but my laptop says I already have the updated version: High Definition Audio Device. What should I do to fix it?

Thanks!

 

Hi and welcome to MG's,
Download the free, Speccy http://majorgeeks.com/Speccy_d6358.html then run Speccy and click File > Save as Text File, then attach the log as per instructions below (note: as Speccy also now lists more data it likely will have your Windows licence serial key also in the log, so look for Operating System and under that Serial Number and delete the code and Save the log)

Then attach your log to your next post as per these instructions http://forums.majorgeeks.com/showthread.php?t=86880

once I have that log I will be able to assist you better.
