How to link/bind different circuits in audio class extension framework

Question

I development two drivers with windows audio class extension framework(ACX). One is a codec driver and the other is an AMP driver. According to "ACX multicircuit composition", I implement the following steps:

1. I create a composite template in the codec driver
2. I create a circuit template for the codec circuit in the codec driver and set the GUID as A
3. I create a circuit template for the AMP circuit in the codec driver and set the GUID as B
4. I add the circuit templates to the composite template, the first is the codec circuit template and the second is the AMP circuit template
5. I add the composite template to the ACX manager
6. I create an acx render circuit with GUID A in the codec driver
7. I create an acx render circuit with GUID B in the AMP driver

As a result, ACX doesn't bind the codec circuit and the AMP circuit together.
