Hi there~
- If you use above image, you do not need to install the driver. You just need to run the arecord -L. Please also take a picture about your mics FPC cable connection in case the wrong connections as well. You can reboot one more time to check if you can see the sound card.
- We tested with latest kernel Linux raspberrypi 4.19.42-v7 and it works as well.
