CPU1/CPU2 and Codec1 are using DPCM.
Thus, it is...

 2xCPU-Codec:
	CPU0 - Codec0
	CPU3 - Codec2

 2xCPU-dummy:
	CPU1 - dummy
	CPU2 - dummy

 1xdummy-Codec:
	dummy - Codec1

Do you mean CPU-dummy + dummy-Codec ?
But anyway, simple-card/audio-graph DPCM support is very limited.
Unfortunately it doesn't have flexibility...

Thank you for your help !!
