--- Comment #5 from Georg Grabler ggrabler@gmail.com 2008-06-08 06:34:16 --- Now, on wine-1.0-rc4 the following was tested:
-> KDE4 - esd (esound daemon) disabled: same behaviour as described -> XFCE - sound daemons disabled: same behaviour as described -> GNOME - sound daemons disabled: same behaviour as described -> Pure X session - all sound daemons disabled: same behaviour as described.
I doubt it's connected to any sound daemon / sound system. I think It's a bug for real.
