Vaio sound

[kt271]

Hello,

I'm having problems with the sound on my CR-series Vaio. I get noises when Windows starts up, but not when I try to play DVDs. I have tried different media players, which makes me think that the problem is with the laptop itself. The speaker is 'working properly' according to the control panel. However, when I run the tests, although I can see the graphic for a sound wave leaving the computer, I cannot hear anything.

Does anyone know what I need to do to get my sound back?

Many thanks,
Katie

Hi Katie,

welcome to Club VAIO..

What model CR do you have and have you recently installed the Vista SP1 update.?

Hi Thalamus,

I have a VGN-CR21S and, yes, I have recently installed the SP1 update. Shortly before the sound made its untimely exit, now that I come to think of it. Do you know what I can do to fix the problem?
