sound in Wine

[Lubos Pintes]

Hello all,
When I started to use, or better said, play with Ubuntu I had a problem 
with sound. Orca and some other applications couldn't play 
simultaneously. I then applied some tricks from Orca wiki and that helped.
Now I probably had the similar problem in Wine. Either Wine and Orca, or 
two Wine applications cannot play something simultaneously. For example, 
the Screamer Radio plays, but crashes when I forget to switch off the 
Orca speech.
Because Wine is inaccessible, I cannot look at winecfg to correct this 
problem. Can someone help me? Something like a registry patch with 
correct settings would be strongly appreciated.
I managed to install eg. MS SAPI SDK 5.1 and Jim Kitchen's games. These 
would probably work if the problem with sound could be corrected.
Many Thanks.
