I'm not DT-man, but it sounds you are misunderstanding about port vs endpoint ?
"port" is for physical interface, "endpoint" is for connection.
If 1 CPU physical interface is connected to 2 Codecs physical interfaces,
above is for it in my understanding.
Can Audio-Graph-Card2 N:M connection [1][2][3] help you ?
Sample is for 2:3 connection, but it should be OK for 1:2.
You need v6.8 or later

Thank you for your help !!
