Sound doesn't work on Sony Vaio VGN-sz480


I'm confused. A Codec is used in an audio player like Media Player 11. If your computer has no sound when it comes on then you need a driver. I looked up your model and found a Realtek driver speciafically for your machine. You can download this at: http://esupport.sony.com/US/perl/swu-list.pl?mdl=VGNS460. If you need an Audio CODEC for your media player I would suggest downloading PowerDVD from download.com to insure that your system sound is working correctly then you can use the Microsoft CODEC installation package to determine the real missing CODEC.

Computer sound not working


ah, try the FN key and holding i down then quickly pressing the end key without releasing fn, then release them.
i have an inspiron laptop computer too just an older version so this might not work, if it doesnt go to control panel, sounds,audio and etc. then go to "Adjust System volume" or one of the other ones under "Sound" which are already up when you click onto that

I WANT SIGMATEL HIGH DEFINITION AUDIO CODEC DRIVER


Here is a link to the latest drivers. You will need to sign in and then download the files.

http://www.download-provider.com/search/sigmatel+high+definition+audio+codec+driver.html?aff.id=1091&aff.subid=1000

I would open Device Manager and delete the current device and then restart the PC. When it starts and detects the new hardware, cancel the installation. Run the setup file that was downloaded. When the installation has completed, restart the PC again and test the sound.

Good luck!

I have no sound in my PC


BrendanG21, I had the same problem this morning. My sound actually quit in the middle of listening to music. Simply restart your computer (it may take a couple tries). If it's saying you have no audio device installed, but everything looks normal when you go into device manager, it's probably the same problem and this should work.

Running Windows XP
Dell B130 laptop
Sound devices listed under my device manager:
Audio Codecs
Legacy Audio Drivers
Legacy Video Capture Devices
Media Control Devices
SigmaTel High Definition Audio CODEC
Video Codecs
