Hi there~

I tested it with pi zero with 2019.7.10 image. It works with 2 mics pi hat. Here is my test result.

So please use the sudo ./uninstall the driver and reboot. Then run the sudo ./install.sh to install it again.

If it still does not work, please copy all the install logs. thanks.

Hi there~

The 2 mics pi hat includes the record and playback functions. So you can see it in arecord and aplay. You can use the audacity to record the audio file. thanks.
