asterisk users - Oct 2003 - Music On Hold with Voicetronix

I have now is music on hold


I have installed ztdummy 


MOH gives me this message now Read 372 bytes of audio while expecting
1600

And no sound


If I run modprobe ztdummy I get no sound 


Even the welcome message etc do not work


And the error message changes to Read 372 bytes of audio while expecting
625



Any ideas
