Solved! Acer Aspire 5733z audio driver for xp

Hello vignesh_03;

This are no WinXP drivers for Aspire 5733z - just Windows 7 drivers.

So your on your own to find one if it's not already in WinXP.
You need to figure out who made the sound chip in that laptop and visit that chip manufacturers website and see if they have made a WindowsXP driver.
