My laptop is a HP Pavilion dv2810us Entertainment Notebook
It all started when I changed my OS from vista to windows 7. Ever since I have been having the "no audio output device installed" problem most of the time. When I go to device manager there is no hint of a sound device, it is as if the laptop can’t recognize/access my sound device.
Sometimes though, when I turn my laptop on, the sound is working perfectly and my device manager shows Conexant smart audio 221 installed. When the laptop has sound working and it goes to sleep, sometimes when it awakes it changes to no audio output device installed. When I try to install the audio driver it says it can’t find the media device. Today I did a OS generalizing procedure to return to default drivers supposedly but it didn’t help. Any comments, clues, suggestions will be VERY MUCH appreciated. I really wanna know why in the world isnt my sound device recognized... :[

I have the same problem, sometimes get audio drivers perfectly and sometimes the device manager just does not show it. I tried the SP39679.exe, run as an administrator, and got the message "unable to locate the device"!
I also tried SP40270.exe, successful installation and seems to work fine, but when I restart the computer, sometimes the audio device just disappear again. I tried to install manually, but the problem persists!

Oh Crap, not worked, after 30 times restarting, the trouble comes back... Still looking for a solution!
