Audio on Counter-Strike

Hello guys
I install opensuse 11 on my machine and I’ve got all properly configured but the sound on counter-strike game doesn’t work, i don’t know how but yesterday I install two sounds packages, alsa-plugins-pulse (1.0.16) and pulseaudio-module-jack (0.9.10) and the game works great with audio and greatest graphics but today the sound is lost again and I don’t know how to work again.

Please help me and sorry about my english, it’s not my native language.

Kindest regards
