Description of problem:

i followed installation process and started Alexa but nothing happened so i tried to check my audio system 
when i tried "aplay /usr/share/sounds/alsa/Front_Center.wav"
"arecord -f S16_LE -r 16000 -D your_input_device test.wav"
"aplay -f S16_LE -r 16000 test.wav"
nothing happened even tho my audio system was working before installtion
and when i try to run it in debug mode 
i get "File "/opt/AlexaPi/src/main.py", line 18, in <module>
    import yaml
ImportError: No module named yaml
"

Hi @EmerickH , I have solved my Issue, I use a I2S Soundcard & the declared GPIO Pins used the same as the Soundcard -.- ^^Very Tricky to found out ! But now all work’s fine ! thanks for your help !!

Same using a speaker bonnet too. May I know how you fixed the issue please? TIA!

I fixed this issue by using the “dummy” platform instead of “raspberrypi”.

Edit your config file sudo nano /etc/opt/AlexaPi/config.yaml

Go to the line platform: and replace device: "raspberrypi" with device: "dummy"

This will configure your device to stop using pins 18, 24 and 25 and you will lose the ability to use led’s and a button press, and since you need 18 for the Adafruit Speaker Bonnet this should let the speakers work again.

I’m sure there is probably a way to just disable the use of pin 18 but since I am not going to be using the leds or a button for my project I didn’t dive deeper into this.

After you can run a test by stopping the Alexa service and restarting it into debug mode. You should hear a “hello” come from your speaker in Alexa’s voice if all goes well. Hopefully that helps!

Stop Alexa service sudo systemctl stop AlexaPi.service Start Alexa service in debug mode python3 /opt/AlexaPi/src/main.py -d

Edit: You can also change which pin you want to use for a button in the config file. For example I changed mine from 18 to 22 and now it works fine with the raspberrypi platform selected.
