I am trying to connect Infineon MEMs capsules (PDM) to the MCH streamer with firmware set for PDM, but I am getting no signal output on the USB.

@umashankar

Unfortunately we've only got limited information here as to what could be the reason... Please provide more details of your setup, wiring, confirm you're using the right fw... many reason why it wouldn't work.. :-)

I am trying to use this card: www.infineon.com/cms/en/product/evaluati.../s2go-memsmic-im69d/
I want to use it in pdm mode as I plan to use 16 of them in a 3rd order Ambisonic microphone. According to Infineon it can be used as PDM mic with the four connections to the capsule when it is split off from the board.
