Realtek sound driver Problem

[Priboni]

Hello,

I have a Sony Vaio VGN-CR131E with Windows Vista home Premium and all of a sudden the sound stopped working. I hear the inicial sounds of start up but then nothing at all.

I tried updating the Realtek HD audio driver but it says it's updated and that there's nothing wrong with it.

I tried get the right driver form vaio support page ( for my model and to vista home premiun) and when installing, it says "this driver is not for your operational system" ( ????) .

When I reinstall the driver with option "let me pick from a list of drivers on my computer" and choose "realtek HIght definition audio" option the sound comes back for a few minutes and then stops again.

This seems started after a windows update, but i do not know what update.

Could someone help me fix this problem?

Thank you in advance.

Hi Priboni and welcome to the forum.

Can you please check that Speaker/HP Realtek High Definition Audio is the default playback device?

Right click the speaker icon in the system tray and select ‘Playback Devices’. You may possibly find that USB Audio Device is marked as default, if so, right click Speaker/HP Realtek High Definition Audio and select ‘Set as Default Device’.

Vista Service Pack 2 has been known to cause this problem.

hi Rich, thanks for your help


My vista have only the service pack 1 and doing what you say I note that only have the Speaker/ HP RealteK High Definition Audio available. And, to windws, its working ok, but ... no sound at all! at least in this moment!

Any other ideas?

i had the same issue on my vaio, but i fixed it (sp2 killed it) what you need to do is write down the SOUND driver model # (not the laptop model), then go to IDT's webpage and find the realtek driver with your model (either that or use google search (e.g. reltek sound driver 1.823) or softpedia/download website) download a .exe and put it on the desktop, then UNINSTALL the current one, so that no sound driver shows up on the sound driver menu, or in the device manager, then activate the .exe, install, then voila, FIXD

well, thats how i did it... (be wary downloading ANY drivers from random websites, some can be malicious)
