Hello, I have a HP Pavilion dv6917, I've installed Windows 7 the sound dissapeared, then returned back to vista and the problem persists, HELP ME PLEASE!!! In device manager it's not shown any audio device...

Sound not working in windows 7
- re-install audio driver
- system restore
- re-install windows 7
- upgrade to vista
- HP 623913 003 Pavilion HPE H8 CTO 656599 001

I know this is common in Windows 8 PC's, never saw it in Vista. I would recommend upgrading the BIOS if an update is available from HP. Really makes no sense as Win 7 is based on Vista's framework. According to HP, they made 20 versions of this model, if you can get back to me with the complete model number (from the sticker on the bottom) that would be a big help.

You can try to install Webcam driver. You've not mentioned your OS; i think you use Windows 7. But HP only support Vista. You can give a try to download and install Vista driver. In most cases it solves the problem.
Here is the links for Vista 64 bit Webcam driver:

Alternatively, you can solve the driver problem by installing HP Software Update

Yes, You can dual boot Windows XP and Vista but you'll be having problem finding drivers if you install Windows XP on this computer since Windows XP supported drivers aren't available on Hp download page. HP has only Windows Vista and Windows 7 drivers for this System.
Hope this helps.
Good Luck.
Thanks for using FixYa.

Hi, you can download the drivers here from hp, select your model number and download the the drivers for Windows XP, either 32 or 64 bit installations.

Make an clean installation of Win 7 and repartition your Hard disk.Use Genuine Windows 7 to avoid blue screen error.AVG 2011 is a very good antivirus.Use Hard disk sanitizer given in Bios settings.Use Tune up utilities 2011or System mechanic latest version.I think your problem will be solved

Hello
HP does not support the drivers for windows 7 for this model, However you can use windows vista drivers on windows 7 as well (as i used the vista sound drivers on windows 7 on dv9000z).

There is no Windows 7 driver listed for your machine. Some have had success installing the Vista audio driver. A link to that driver is listed below.

Well, this may make you think twice:

I bought a presario from circuit city last year, and I paid $200 to downgrade to XP. Everything was fine until it crashed last week. IT went completely bizzerk. HP won't provide support, cause I changed it. Circuit City is out of business, not much help there.

Basically, I am completely #$%%@@.

I am now paying to get Vista put back in. :-(
