[Bf-committers] No Sound in BGE on OSX, Can someone update dep's?

Sun May 3 12:51:06 CEST 2009

Hi,

Note that we've released intel osx versions always without sound, it  
has a warning for it on the download page.
Unless the platform maintainer (with help?) can get it to work  
reliably, we could skip it as release target. It's really a development  
topic?
