I have downloaded Raspbian Stretch with desktop released on April 08, 2019. HAT mics work with the default OS without issue but as soon as I perform the update by sudo apt-get update, mic stop working. Its not even detecting the device for arecord. Any help is appreciated.

Hi there,

I use the 2019-04-08 image and test with 2 mics well. if you can not get the mics work, you can de-install the driver and install it back. thanks.
