[Wine] Sound Problem

[Zinnoc]

Hello guys, i have a sound problem with Wine 1.0.1 (is the same on every version) on Ubuntu Linux v9.04, when i start play some game for Windows, like Counter-Strike 1.6, in the beginning i have perfect sound, but when i'm playing more than 10-15 minutes and my sound disappeares, when i restart the game, the sound is back, but happens again in 10-15 minutes, any ideas ?  :?
