Windows 7: Volume/Mute do not work Dv9823 Windows 7

Volume and Mute buttons do not work with Windows 7
I did a clean install of Windows 7 on my Hp DV9823CL. The quickplay and dvd buttons work,but the volume and mute buttons do not. This is what I sent HP:

problem description : I did a clean install of Windows 7. Prior to the clean install all quickplay buttons worked fine. Now the quickplay and the dvd buttons work,but the volume and mute buttons do not work.
troubleshooting : I reinstalled quickplay, as well as the quick play buton drivers that are listed. I also did a troubleshoot that worked once when I removed the battery and put it back in. This also does not fix the problem.

This is what their repsonse was:

Thank you for contacting HP Total Care.
Scott, as I was checking your notebook’s specification I found that your notebook was shipped with Windows Vista. Your notebook is not upgradable to windows 7 as there is no driver available your notebook’s driver page. Your notebook is design to perform its best in Windows Vista. So I request you to get back to the original operating system.
If you need further assistance, please reply to this message and we will be happy to assist you further.
For information on keeping your HP and Compaq products up and running, please visit our Web site

So do they really think, I should dump a better OS and go back to Vista,just because the volume and mute buttons do not work..there must be a solution.

Advise and response that has been given so far:

scott,
I remember getting such a msg from HP one time. I was stubborn and got hold of another person at HP who pointed me to the info I needed. Trouble is your inquiry gets handled by a Tier 1 newbee who doesn't know up from down and only has a script of answers to questions. Hang in there.

Also, try out the WIN + X combo You will possibly find what you are looking for.
The WIN key is that one with the funny looking wavy flag on it.

For Microsoft's evaluation of your hardware and software compatibility, please use:

Thanks,
I will try it ( I am working late the next couple day's,so I won't be able to untill then ). Also, I work in retail (electronics area) and have done all the common troubleshooting. I did run the advisor,prior to install, and there were no issues found.

Thanks again,
Scott

Try the Vista Drivers
Many hardware drivers for Vista will work for Windows 7.

I think HP uses a program to monitor the "extra" buttons like volume, play, mute, etc. Try the Vista version of that program for your laptop.

Also, look at the specs for a later version of your laptop that HP is selling with Windows 7, see if a newer version of that program is available for the newer PC and try it.

I used the drivers for newer model Dell Inspirons when I upgraded my 6000 to Vista, some worked, some did not. you may have to try several versions to get one that works right.

Also see if there are any user forums on HP's website, someone there may have already solved your problem.

Volume Slider does not work windows 7 hp dv9823/9000 Thanks, at least the Win + key took my to the Windows Mobility Center, which then lets me us the slider again (even though at times speratically). You need to open the center to make it work. I tried changing the drivers,with still no luck. thanks everyone for your help.

thanks,but the hp support forum,was no help on this one
