Crysis audio problem on windows 7?

This is a very lengthy text,please read is thoroughly..



My problem is, whenever i play crysis 1 or crysis warhead, the sound gets slower then the game(display). I here the sound as if everything is happening in a tunnel or a cave. I mean its like reverb, that too very slow....but it doesn't happen while playing songs or videos.

it never happened when i played this game on windows xp. Other game like COD Black Ops runs a bit slower than it ran on Xp, and sometimes, that crysis sound problem comes in this game too. But in a lesser amount (for 1 or 2 seconds)....

The other games like NFS Hot Persuit and Devil May Cry 4 runs smoothly with no sound issues....



One more thing, for sometime in some levels the sound is ok in crysis %26amp; warhead. But in some action scenes and sometimes for no reasons the sounds starts cracking and gets slow....

I tried reducing the visual and audio effects to LOW form game's advanced settings. but saw no improvement. Whenever i install realtek audio driver for windows 7, the sound gets worse and i can here distortion on playing songs and videos also.

I also tried changing the audio frequency from control panel%26gt;sound%26gt;playback devices.....

But no joy.



I think it may be because of

1%26gt;installing windows updates

2%26gt;i installed directx 9.0c after installing windows 7 coz i didn't knew windows 7 has pre installed directx 11. May be my directx installation overwrited some directx 11 files.

3%26gt;when i tried installing windows 7 from booting, it said that the drivers are not found.

so i installed it from windows xp, from my computer. the message didn't came and it was a clean installation. i saw the the drivers are properly installed. I removed windows xp files from windows.old.

But nw after shuting down the lights of my computer don't turn off. i have to manualy do it by pressing the CPU button for some time. IS IT GOOD??

PLEASE HELP.....FOR BOTH THE PROBLEMS( sound %26amp; lights)

This can happen due to several reasons.

I will try to point some reasons

1) Proper sound Driver

2) Broadband speed if you are playing online.

3) Registry issues

4) Dedicated Graphics Card
