[orca-list] my audio only works within orca screen magnifier window

[Yifeng <Yifeng Luo Sun COM>]

Hello,

I have a Mac OS, installed sun virtual box, then installed open solaris 
2009.06.

Then I downloaded audio driver from 
http://www.4front-tech.com/release/oss-solaris-v4.1-1052-i386.pkg

My audio works fine. And then I invoke orca from terminal command line 
using root as id.

After setting language preference and all the keyboard preference, I 
logout and login my open solaris as directed.

Type orca from command line, this brings up orca screen magnifier 
window, my audio only works within the window, that is, it reads help 
contents etc, but when I invoke my firefox browser, system keeps quiet.

Can someone help me? How can I make orca "talk" and "read" browser 
information for me when I navigate?

Thanks
