No sound in some games in wine

view story

http://ubuntuforums.org – Hi, I've been having problems with getting sound to work with two out of three of my games that I have installed with steam on wine. I've installed Borderlands 2, Dead Island, and Portal 2. Borderlands 2 works flawlessly and sound is great. However, Dead Island and Portal 2, do not have sound. Although the graphics, and the game play is fine, there is no sound. I'm running Ubuntu 12.10 64-bit with Wine version 1.5.19. Under audio tab in winecfg, the selected driver is winepulse.drv, and the output device is set to system default. When I click test sound, there is a 2 or 3 second delay bef (Hardware)
