Sound Problem, need kext?

[Jasmeru]

Hi guys!

First, I'm sorry if you don't understand me, my first language isn't English ^^

 

Here's the problem:

Last week, I downloaded Mac Os X Leopard (10.5.2) from pcwiz. It took me 6 days to make ethernet works, and now... I've problem with the sound. I can listen to music... but it's laggy or I don't know what. I think I need to download some kext file, but I don't even know what is my sound card :

 

 

 

 

As you can see, Windows tells me that I have Realtek High Definition Audio or Ati Function Driver for High Definition Audio - ATI AA01

The Mac in VMware Worksation 6.5 tell me that I have AC97 Audio (PM)

And Everest think that I have ATI RADEON HDMI @ ATI RV770/790 - High Definition Audio Controller or Realtek ALC888/1200 @ Intel 82801JB ICH10 - High Definition Audio Controller

 

So... who's right? How I am suppose to know what Sound Card I have? And what am I suppose to do? Install kext? Wich one? I really need your help guys!
