[Wine] mp3 game produces no sound in Wine 1.0

[louy2k]

Hello dear all,
my windows game plays mp3 sounds. (the game is C-evo)
the game runs fine under wine except for mp3 sounds.
my platform is Fedora 9-WINE 1.0.
The audio test in winecfg works fine.

Trying to solve the problem, I"ve installed a mp3 Fraunhofer codec in wine (an exe file) ; problem remains.

At linux level I have no mp3 codec installed.

Does any one has a clue to such problem ?
