So I bought this $10 Google Assistant from Amazon Prime.  Only to find out it doesnt work as easily as advertised.   It comes with a modified Raspian distro.  Here are the latest steps I did to get mine to work.  I spent a half a day muddling through commands,  so im not sure if previous steps might have led to it working but hope this helps someone…Note the audio volume in the navigation is disabled, but the google voice does work (when I did get the audio driver working, the google voice via python was not)

cd ~/AIY-projects-python

sudo scripts/install-alsa-config.sh

Outputted:

Renaming /home/pi/.asoundrc to /home/pi/.asoundrc.bak…
Renaming /etc/asound.conf to /etc/asound.conf.bak…
Installed voiceHAT ALSA config at /etc/asound.conf
Installed voiceHAT ALSA config at /home/pi/.asoundrc

I tried:  python checkpoints/check_audio.py

Outputted:

ImportError: No module named aiy.audio

python3 checkpoints/check_audio.py

Worked…Playing test sound….

So the module only works when you declare the Python3…..

before this i did compile the drivers by going to the /home/pi/drivers-raspi folder, and ran

sudo ./build.sh

the script appears to compile the drivers and created a boot/config.txt file….I believe the parameters in the config.txt file are run when the image boots up…here is a copy of mine in case anyone else may need to compare:

I added dtoverlay=googlevoicehat-soundcard to mine, I also added dtparam=audio=on but the driver script appears to have commented dtparam=audio=on  out to #dtparam=audio=on
