KDE sound via netword/esd

Since I updated my installation to openSuSE 11 it is not possible to get sound via network on a windows workstation with esd-sound server. As X11-Server on Windows I use XMing.
After login with XDMCP-Session and listening soundserver on my Windows Workstation not even the ESPEAKER-Variable is set in the environment. Also nothing happend, if I do it in my .profile-script.
Using NX-Server/NX-Client sound works fine…
How can I get working my sound via esd which works fine using 10.3???:’(
