Hi,

I have a problem with the installation of Respeaker 2 Mic Hat.
Raspberry PI 3
Distributor ID: Raspbian
Release: 9.4
Codename: stretch
I just only on this Raspberry "snips"

And I have this error when I try to record :
arecord: main:788: audio open error: Device or resource busy

I tried to remove and reinstall but the situation it is the same.
It works with a simple USB Mic.
Thanks for you help.
