Go here and download the appropriate driver for your Operating System (XP, Vista, Windows 7, etc)

Be sure to download the appropriate version (i.e. 32 bit or 64 bit)

You may have to uninstall the current driver and then load the on you have downloaded./

Drivers webcam for sony vaio ar520, windows7

Please install the Sony Shared Library and then install the Original Sony Visual Communication Camera to resolve the Camera issue. If you installed Windows 7 32 bit Operating System also, you can try installing the same Driver as the Drivers for Windows Vista should work under Windows 7 Operating System.
Sony Shared Library is the System component which makes the installation of the other Drivers compatible with the Computer.

I installed a Realtek HDAUDIO driver on my sonyVAIO Notebook of model-PCG-7L1M but still no sound is produced.The notebook speakers are workin fine.What should I do?

It would seem that you have the wrong driver installed!!
The driver you need is the Original - SigmaTel® High Definition Audio Device Driver
Which can be found here along with all the other drivers for your laptop!

Good Luck!

Intel945GNT audio driver is not installin?object not found error?

I found this on CNET after googling "device object not present". You can find the whole discussion here:

Solved Device Object not present on VAIO VGN-FE31Z by Kevski2 - 11/23/06 3:22 PM In reply to: No sound on Dell Inspiron 5100 by tlove258 After a whole day on this particular issue I managed to resolve it - well for me at least! I had just done a clean install of Windows XP Pro (with SP2 included) on a Sony Vaio VGN-FE31Z.

It seems that the order you install the device drivers is critical, and unfortunately, like many other out there it would seem, I got the order wrong and so was stuck with the error message "Device Object not present..." when ever I tried to install the Audio drivers. The device was showing in the Device Manager as "PCI device" with the usual black cross on a yellow background. I knew it was an audio device, I also had the "as supplied" Sony drivers in "C:\Drivers" but running the setup.exe still caused the error message above.

I had done numerous "Windows Updates" but curiously enough I did not have either KB888111 nor KB835221 installed. After much googling I found a copy of the file kb888111.exe on a download site and tried it.


Immediately after the install of KB888111.exe, the Vaio (by itself - no clicking by me) started to detect the SigmaTel High Definition Audio and install drivers etc.

Wonderful - or so I thought. BUt even when all this was done and after a reboot - still no audio device. I then ran the Setup.exe again and this time it did not come up with the error, and the sound drivers (and Modem - now what is the tie up there I wonder?) installed, the sound device was recognised and I now have wonderful sound. Well, **** actually because the speaker are inbuilt diaphrams and not something of a higher cost/quality - but you get the idea.

Hope this helps someone. Excuse any typo's, mis-capitalisations etc - I've had three beers this evening while I have been pulling out what little hair I have left!

karplandius, Your laptop was made for VISTA. There are no drivers on the Sony website. What I would do is contact Sony and see if any VISTA drivers will work with your laptop.

You can contact them here:

Please let me know how you make out!!
