Time stamp problem

Hi,


I have a program that can play and record at the same time.  The audio IO procs are always running for the active window.  If nothing is playing, it just fills the buffers with zeros.  If it's not recording, it doesn't call AudioUnitRender().  When a new window is opened, it stops the IO procs for the old window, and starts them for the new window.  That's when the time stamp's mSampleTime starts giving you bad values.  When you put a 1 second delay between stopping and starting the IO procs it works fine.

Any ideas what could be causing this?

thanks
Jeff
