Hello:
we are currently developing an integrated system using Mini PCIe with the EC200A module and we coupled the ALC5616 codec, however, despite following the documentation we were unable to record audio output from the design, we tested our code and implementation in the Mini PCIe EVB kit product, in the EVB everything works perfectly, because we have been trying to solve this problem for a year, we would like to know if you could provide the schematics and the bill of materials, to check if we have any fault in our design since we tried to develop the entire system based on your indications from the documentation of the technical sheets of the products, PCB guidelines, user guides from EC200 and EVB kit.
Any feedback or input is welcomed and appreciated!
Thanks again!
Camilo
