Dear Customer, We suspect some error during sudo ./install.sh. We suggest change to your http://www.raspbian.org/RaspbianMirrors and try it again. If it still does not work, we upload a 4 mic image in https://drive.google.com/open?id=15yEZE ... hV4OVimQ_7 and it works with 2 mic as well. thanks.

Hi !
I got the same error and I changed operating system from Ver.20180217 to Ver.20171129. I could solve this problem.
But finally another symptom appeared. I think two microphones are not react.

And another question...
Which type should I register this device to Google Assistant SDK ?

Please teach. Thank you.

Hi There,

I've the same issue, using your binary to run.

I'm having a low voltage alert, do you think it can be linked ?
However, I'm using Rpi 3B+, camera V2, 7" official display, and official power supply.

Many thanks.

Fred

Hi Fred

If you have the power drop, please plug a usb power cable to 2 mics pi hat USB port. it is designed if we connect the speaker on the Pi HAT. But i do not think errors are related with power drop. We use the RASPBIAN STRETCH WITH DESKTOP 2018.4.18 image for the testing. it works well. please download it from https://www.raspberrypi.org/downloads/raspbian/. please copy all the logs during ./install.sh and we can see if it is related with driver installation. thanks.
