No audio at all

Hello everyone, I just updated to Windows 7 Professional about 2 weeks ago. I keep having problems with my audio, apparently I do not have any sound driver/device installed.

I tried to narrow the problem by doing several system restores as the audio has worked until recently. I believe I accidentally uninstalled something while in the Add/Remove Programs tab of the Control Panel. I was trying to get rid of things that I do not use like I-Tunes..

After several system restores, I could not figure out the problem so I went to the Real-tek website because apparently that is standard. I downloaded the 32-bit driver for Windows 7 and installed it. Restarted my computer and the audio came on.

Went to a friend's house with no wi-fi (couldn't download anything), all I did was write and listen to music off my lap top. Came back to my home the next day, turned the computer on and now I apparently don't have any devices installed.

I tried to re-install the audio driver/device from the Real-tek website, and it didn't work. I've tried that twice, with the restart of the computer.

Can someone please assist me with this? I'm almost to the point of saving everything on an external hard drive and re-installing Windows.

Thank You.

Thank you for the quick response - I checked on the bottom of my laptop and it says HP Pavillion dv 2500, it also says dv27 15nr.

Do you need more information then this?

Thank You.

Product number is KC453UEA#ABA

No i found it .. But it is more or less the same Driver i posted

Thank you for your help - However I was given this message after trying to install off the first link.



A balloon popped up in the lower right hand corner that said a driver was not properly installed and requested I click for more information. This was the screen that popped up:



I am downloading the one off the 2nd link but I am concerned that the "System Requirements" for that download apparently require Windows Vista and I am running on Windows 7 Professional. The laptop when it was originally bought, was running Vista but I've recently updated. Would that change things at all?

Follow Maxie's lead, but in between could you post some informational screen shots

• Control Panel -> Sound -> Playback tab
• Control Panel -> Sound -> Sounds tab
• Device Manager -> Sound, video, and game controllers

Thank you for the reply:

Playback Tab:



Sounds Tab:



Device Manager Tab:



I was unable to locate "Sound, video, and game controllers" on this screen. This troubles me as it is not even an option unless I missed. If that is the case, I apologize.

Thank you.

Hi there .. First Install the Chipset Driver from the Link i gave you .. Right click on the Download and run as admin .. After that try the sound Driver .. I did know they where for Vista but they often work with Windows 7 ..

Thank You - The 2nd link that you gave me, I clicked on that one and scrolled down to the chipset and clicked on the first one. Downloaded it and right clicked it and tried to install it with it running as administrator. This is the message I got:



Do you think its other programs that are blocking the process?

Thank You.

Back to the issue: What region is the machine from? NR indicates non regional. Sometimes we have to go to the HP regional site to find the information we need. UK, FR, IT... etc

The laptop was purchased in the US as far as I know, a family member's employer purchased the laptop a few years ago for work. They just bought him a new one and he gave me this one about 2 weeks ago as I am in the military and my old laptop was from 2004.

Thank You.
