Please provide more details of your setup, wiring, confirm you're using the right fw... many reason why it wouldn't work.. DevTeam

umashankar Offline Fresh Boarder Posts: 3 Karma: 0	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.
