No Audio Output Device is installed. Windows 7.  

Hey guys, English is not my first language so I'm not familiar with the Computer Science vocabulary. I've had a Pavilion dv9700, Model # dv9819wm, for approximately 2 years. My hard drive failed and the guys at my school were able to recover 60 GB of files but most of them don't have an ordinary format. They are just saved on a folder on my desktop. They installed Windows 7, (It was Windows Vista before the failure) and I've been having problems with the coprocessor and "ethernet" drivers. Yesterday I uninstalled the "ethernet" driver and when my laptop rebooted the audio driver was nowhere, (obviously I have no audio), which was surprising since that was not the one I uninstalled. My Sound device is not shown on Device Manager either. I uploaded some applications that identify missing drivers and apparently the sound driver is the newest one available. I got on BIOS and the sound button was enabled. I went to HP's website and the only audio drivers offered for my laptop model were for OS Vista. When I try to automatically install the driver from another HP application it says something like my "Compatibility..." is not permitting a correct installation. First, what is going on? and is there any way I can get my pictures and videos from those 60 GB into a normal format/structure?. Thank you. Hope the post is not too long but I tried to give as much information as possible.

Hi "pebbly". As soon as the installation finishes, this message appears, "Driver installation failed: Could not find the device for this driver". Thank you though.

Which one did you download seeing as HP as both a Conexant and a Realtek driver listed? It will be one or the other so if you haven't yet, download and try the other and it should install.

Mine is a "Conexant High Definition SmartAudio 221". Also, when I click on the audio icon on the bottom right of my screen. Troubleshooting runs and finds "Hardware changes might no have been detected....Detected"...and a yellow exclamation icon.
