I am really fed up with this nonsense.
After Flash went silent on me (see previous post), I have downloaded and installed the Flash 9 beta, which did not fix the problem.
Then I've been able to hunt down (and it is damn well hidden) a place where other versions than 9 are available:
So I uninstalled version 9, then tried the updater for version 8 only to find out that it wouldn't install anything, because it was an updater, not an installer.
The real installers are far better hidden than that:
Inside those zipfiles, there are both the Mac and the Windows versions.
But sadly, even after re-installing 8.0 r24, still no sound.
Any ideas how to fix this mess ?
Just fixed it myself, it was incredibly simple:
I dumped the complete Macromedia Folder that lives in ~/Library/Preferences
