No sound after windows 7 !

Hello,

I installed windows 7 on my HP dv1000 laptop. Windows works flawlessly but there is NO SOUND!
I tried to install the Microsoft UAA Bus Driver for High Definition Audio but I have an error message:"HPQNT.dll.failed"
What is going wrong ? How to fix this error to install UAA?
Please somebody has any idea, solution ?
I installed all imaginable driver (realtek...etc) but no sound!

Thanks for help

Thank you for your answer.
Actually, I have already installed this driver, with many others from HP website, but this didn't resolve the problem!
I have to try the Microsoft UAA high definition driver but I can't installed it, as there is an error message about the HPQNT.dll!
I think if I can fix this DLL issue, the problem might be solved! Microsoft UAA audio driver should resolve my problem but I can't installed it because of the DLL error!

According to HP the only drivers for your computer are the XP ones. There is nothing newer and your model is not supported under win 7. You may be able to use the XP driver if you install it in compatibility mode.
(right click the insaller>properties>compatibility>XP)


Let us know if you need help

Sound has come back now! Thank you very much for your answer!
I don't know which solution solvedit but it works now and I can hear sounds on my laptop but....but there is still another problem: recording is not working!
I cant record any voice!
Recording device (built-in micro) is not working at all! I can hear sounds but can't record any sound! Others can't hear me neither! Although, driver is working correctly as figured out in the following screenshots:
Is there any abnormality with these devices ? I disabled, enabled, installed/unistalled all of these devices/drivers without success!

On the 4th screen shot (last one) I don't know why "Restore default" button and scrolling list are disabled, and Microphone is "Currently unavaliable"
?!
Really, fed-up with HP and windows 7 !
