Hello,

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.

https://www.sony-asia.com/electronics/support/laptop-pc-vgn-series/vgn-sz433n

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.
