Sound Problem in My Intel Motherboard

Hi, I am a beginner in the world of technology. Recently I have learnt how to install operating system in a fresh computer and tried to practice on my desktop computer. But after installing the operating system I am not getting any sound from my pc.
Motherboard model is Intel DG965RY. In the device manager I don’t see any problem and sound device is showing high definition audio device. To get back the sound I tried by reinstalling the sound driver and don’t see any error message during the process. When I try to play any kind of audio file, it says bad sound driver detected. Somebody please help me.
