I am not getting any audio/sound from speakers/headphones in my sony vaio VGN-SZ433N Laptop.
1) I was using windows XP SP2. So, I uninstalled the Windows and installed win Vista Home Premium 32 bit and downloaded all drivers from Sony Support Website.

and installed chipset driver. It worked properly and then try to install the audio driver but a message displays that this is not intended for your model. How come a chipset driver is OK and not the audio driver.

2) I checked device manager and in sounds, it mentions only high definition audio driver option and nothing else. Don't understand whether i am having a right driver installed or not.

Please help me out to get the sound of my laptop.
