Sound Problem

[neo]

I have installed Vista in my system with P4 Dual Core 2.8Ghz + D101GCC2 Motherboard with on board graphics ATI Xpress 200 and HD Audio. HD Audio Drivers are automatically installed by Vista but I can't hear any sound.

After the new driver has downloaded and installation performed, every thing go write and hardware has deteted successfully. when I click on tray icon, it shows all app and windows sound are woring properly and also device manager shows this. But problem still remain.

these screenshots are taken while trying to play mp3 file in Windows Media Player, Winamp and play test sound.
