I checked if an application used sound and killed them , but nothing more ; no sound. I uninstalled pulseaudio and linux didn't start kde when I rebooted ;-) There is a probleme betwean mandriva 2008.1 and wine (I reinstalled them 2 times and I had the same problem-no sound under wine) ; Then I installed mandriva 2008.0 and everything work fine at the first strike. I think it is pulse audio wich cause problem with wine but I can't confirm , I will do some more tests.
