these are my specs, the first thing is that although the sys model says 9700 the bottom of my comp says 9925nr so idk whats up with that now onto my big big issue:
about two days ago my sound went mysteriously off and then i noticed that the sound driver went mysteriously missing and now i had the no audio output device message. so naturally first i tried to reinstall the driver using the driver restore but that failed, then i did a system restore to a day or 2 b4 and it was fine then a few hours later it happened again except this time the sys restore didnt fix it. its been two days and still no sound ive tried the following solutions:
--------------installing the following(all of which failed):
----------I tried adding legacy hardware and under conexant no audio drivers were listed so i tried the realtek and although it did install i got a code 10.
so any suggestions i need help ASAP

Do another System Restore to get back to where you were. Then shutdown and try a hard reset. good luck!
1-remove power cord and battery
2-press power button for 30 seconds
3-reinstall battery and power cord

I have the same issue
HP pavilion dv9000/dv9815nr
AMD turion 64 X2 TL-60
vista ultimate sp2 32-bit
Sound was disabled after a windows update I rolled back and everything was fine. a day later Microsoft updated again no audio again. Tried a rollback yet again did not work this time. So i checked for a virus,spyware, malware etc. Nothing tried to reinstall hardware. Conexant Hardware not listed realteck installed but did not work (code 10) Decided I needed to clean up the HD any way backed up all files and did a total system recovery. This seemed to work. Microsoft needed updates I installed them 1 at a time good for about an hour then audio gone again. Took the cover off the laptop checked all connections and everything is fine there all hardware is connected(this is my job so yes I know how to do it properly).
Rolling back no longer works and I do not want to do another recovery it takes to long and already failed to resolve the issue. Microsoft provided a hotfix which did not fix anything. Hard reset also did not do it so what is the next step because it seems to be a software conflict from microsoft update but i can't pinpoint which one.

So leemags, did you ever find a solution to this problem? I just encountered last week and did exactly as you stated. I was able to get the audio back, but only temporarily. Now I can't even get it back temporarily. I thought it was a PC problem but it appears MAC users are experiencing this too.
WOULD REALLY LIKE TO KNOW A SOLUTION.

I have had the same difficulty and I even tried not only all that you did, but I also finally just downloaded Linux Ubuntu 10.10. Still no sound!!! The problem seems to be one where:
1) The physical devices only work properly in Windows-it's proprietary device design.
2) The physical device has "decided" that it wants to resign.
3) Downloading any system fixes will not work.
4) According to HP, the Vista system is part of the problem.
5) Very possibly the main problem is Microsoft and it's updates. When I finished downloading the SP2 updates, that was when the sound found it's get up and go, and got up and went!
I need to find an audio card that will work without Windows and then install it. And then go back to Linux!!!

Hi, I know this is a bit old, but same here. I have Ubuntu 10.10, but just had this thought...my Ubuntu is running off a mirror file in WIndows (wubi), so perhaps the reason no devices are showing in Ubuntu just as Windows, is that any confliction causing the lack of sound in Windows is being mirrored into Ubuntu.
So, a true partition might be a way to get sound back in Ubuntu. Unless it's a hardware problem.
