Speech Web Application using SALT

Question

Dear all, I have developed a voice-enabled(SALT) web application on Windows 2003 platform using SASDK Beta 4 using VisualStudio.NET. I run the application with Speech Plug-in(Beta 3) installed, it is working fine. But, if I run the application with Speech Plug-in(Beta 4) installed, there is a recognition but there is no sound(i.e. prompts are not playing). Could anyone help on this ? Regards, Sateesh
