No sound device found?

Your sound drivers are corrupted you should 1.go in control panel 2.hardware and sound 3.device manager 4.right click your sound driver and uninstall it 5.reboot your computer that should fix your problem

The main reason would be sound drivers, i recommend uninstalling the drivers in the control panel, hardware sound, device manager, right click, uninstall.. and reboot afterwards, if that doesn't fix the problem than it could be the sound card it blew out, i recommend buying a new sound card.... try hooking up a pair of speakers to it, if you get sound, then its the speakers on your laptop that are bad... good luck!!

you need to uninstall the youcam driver and then reinstall the driver then it should work.

Have you checked your device manager? Make sure you have installed the right driver for you computer. I suggest you try to upgrade drivers for your computer first, then visit HP's website to check if there's any firmware upgrade for you machine. Feel free to visit DigitalSupportTech for getting help.

go to hp.com and click on support and find the tab that says driver download click on it and type in your laptop name and under audio download the file that says something about sound.

well u need to tell me which series of pavilion dv2000 Note it's located on the label as in this example: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01087277&lc=en&cc=us

you need to go to http://www.hp.com and choose your computer from the laptop list clcik on help and support, next put your computer modle into the search box or have it auto detect your system, then download the drivers you need and this will fix your problem, do not remove drivers to make more space..

Did you 'turn off' the AUTOPLAY feature of the CD\DVD ? When the player "runs two times at startup", it is trying to find the program on the disc.2nd- Look in internet for HP dv6000 cd\dvd drive replacement.(If that is the ""exact match for the product"" you wrote about)
3rd.goto CONTROL PANEL>SYSTEM>HARDWARE>DEVICE MANAGER and look up cd\dvd and uninstall it. REBOOT, when your system comes back it will try to find the cd\dvd. If it does not, it is damaged (kaput!), must be replaced. If Windows finds the cd\dvd drive and reinstalls the drivers, but it does not work, then the heads are dirty or damaged.That Windows found the dvd\cd means that the circuit on the device works.

Ok have a look at the bottom right hand side of the screen at the system tray, if there is a red round circle on the speaker icon then the speakers are muted, you may have to active them via the keyboard toggle, hold down Fn and locate the sound keys (usually the "F" keys), If this doesn't work go back into device manager and uninstall the sound drivers, reboot the laptop and the drivers will re-install by themselves, that should do the trick

Good luck
