[Wine] Wine has lost sound on Kubuntu 9.10

[Lisi]

Help!  What should I look at?  It was working well - and suddenly it isn't.  
Clearly something happened or I did something - but what?  Where do I begin 
to look?  

I have checked the settings in winecfg, and they look exactly the same as they 
did when sound was working - and sound is fine still in other applications.

This is urgent and mission critical.  It would be, wouldn't it? :-(

TIA
