HP dv6565us messed up! Help!

A year ago something odd happened. The soundcard just turned off, the computer crashed and turned off. When it was back up, the soundcard could not be founded anymore, and i've got like fourty "Unknow Device on High Definition Audio Bus" on my device manager.

Like that:





I've tried everything, used all the recovery options from hp, even the restoration to the recorded image of the system. Tried to reinstall all drivers and nothing solved.

The system kept throwing windows nonstop. Like that:


So, what i did was just disabling the High Definition Audio Bus on System Device, and bought an Usb external sound card. Ok, its working great, BUT, i obviously dont get any sounds from the internal notebook speaker or microphone. And neither the mute light, on quickplay buttons, works. Its red all the time. Muted or not.

BUT, i want to give this notebook to my wife, but i still use this external soundcard for my musical recordings. So i really needed to figure out a way to solve this. I've contacted the HP Support Staff, none of them could help me. Warranty was over months before the problem. Obvioulsy. =/


So, anyone have any suggestions?
PLEASE, help me. It has been a constant struggle, but its the first time I ask for help in a forum.

(btw, im brazilian, and i dont know if i was clear about the problem)

Help me, i'll thank you forever.
Thanks!

Its Vista.

Thank you for the reply.
I'll now check the stickies.

=)

im going to install now this realtek driver.

since i've installed a ton of drivers, including from hp, and none of them worked, lets hope this one does.


btw, forgot to mention, fingerprint reader does not work either.
It recognizes the hardware, but it just cant be used.

=/

It didnt work...

Same error messages..

I dont know if its useful to inform, but when i was using the Remote Access to another computer, when i get some sound from there, my notebook speaker beeps. just BEEP!, but its a sign that its not dead. So, it gets even more confusing ;S

What can I do now?

Hey, i've been disconnected these days. Got it back this morning. But...


No results.
Those troubleshootings clears only problems when the device is being recognized by the system.

But this is what i get:





And do you know what sucks more? There is no authorized service in my state. And obviously my lame warranty doesnt cover even the smell. <sadly lol>


I didnt want to hand my notebook to some guy who just claims to know a lot. And I'm afraid to be charged overpriced, since the value of it has fallen down tremendously.


So... is there anything else we can try? =/


Thx for all the help, btw.

After a long time trying everything, i restored the notebook by reformatting to factory defaults.

The fingerprint device is now working again, but, the sound problem remains. Thats a nightmare =/.

I could get some more info about it, just doesnt know if it is useful:
