tried removing all the vst plugins from the directory called vst, than 
running ardour without any plugins, but than trying to "close session" i 
get the same behavior that  i  am only able  to kill ardour.

now i copied back the vst´s to the vst directory, and still wine is not 
complaining about any alsa stuff anymore:
