Wrong audio driver on 3Dp Chip. In multimedia i had "Multimedia Card : Realtek AC97 Audio". i Installed the driver, but the driver is not compatible and i dont hear any sound using "Realtek AC97 Audio". So i downloaded manually on the website at:

Thanks Costa.
But in this case, 3DP Chip is right.
1. 'Realtek AC97 Audio' : Open the Alcxwdm22.inf in ASRock driver, check the 'Realtek AC97 Audio'.
2. Driver compatibility : This driver(in 3DP Chip) is compatible with your audio device. Open the inf files, check the compatibility.
Sometimes there can be a problem. But this is not driver problem. Automatic installation isn't perfect. So you can install the driver in Device manager.
I encourage you to install the driver in 3DP Chip because ASRock driver(11/17/2004,5.10.00.5750) is older than driver in 3DP Chip(09/24/2008,5.10.00.6300).
Thanks!
