I would like to start by stating my computer specs. It is an HP Pavilion dv6700 (Entertainment Notebook PC), model dv6815nr, Windows Vista Home Premium.
Today I installed the newest version of Adobe Flash Player, which caused Firefox to crash. So I downloaded uninstall_flash_player.exe from the Adobe website. Then I downloaded the archive of Flash Player 10, and installed the previous version. When I restarted my computer to allow the changes to take effect, it would not restart correctly. The power light would come on for a few seconds, it would seem like it was starting up, and then it would crash, only to try to restart again. It repeated this process until I held down the power button to manually shut it down. After a while it was able to start up correctly, only this was when the audio problems started.
First, it said "HP QuickTouch On Screen Display has stopped working." I initially thought this was the main problem, but I realized having no audio devices installed was the real problem. When I hovered the cursor over the audio symbol on the bottom right of the screen, I got this message:
When I right click the audio symbol and click playback device, it says "No audio devices are installed."
I opened the Recovery Manager and reinstalled the "HDAUDIO Soft Data Fax Modem with Smart CP" since it seemed like it might be an audio driver or something. That didn't work, and neither did a system restore to two days ago (5-29-09). I also tried installing something from "RealTek" which I think was an audio driver, but that did nothing.
I tried to find an audio driver on the HP website but I didn't see anything related to audio.
Can anyone help at all? Thanks for any advice.

I fixed the problem a couple minutes after posting this, despite that I had been trying to fix it for HOURS. I went to Recovery Manager and reinstalled the "Contexant HD-Audio SmartAMC HD2 Driver" and restarted my computer.

Go to Hewlett Packard - Enter the product name / number. Be sure to check the additional information, like how to install the driver or troubleshooting guides.

I read the replies. Then checked the Programme files and it shows that Conextant HD Audio and Realtec High Definitation Audio both installed. However, the Hardware and Sound tab in the Control Panel - Device Manager - Sound still showing 'No Audio Devices Installed'
What should I do?
