I have a problem with the installation of Respeaker 2 Mic Hat.
Raspberry PI 3
Distributor ID: Raspbian
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.
it seems other process occupied the mics. please run ps -A to see any arecord process and kill it. then try it again. thanks.
