Raspberry Pi FAQs - rreimi/alexa-avs-sample-app GitHub Wiki

I got the Raspberry Pi working with AVS, but I can’t hear the audio response from Alexa

Check to see if you are seeing the response coming through on the Terminal and if you see the response cards on your Alexa app. If yes, you probably need to force audio through local 3.5mm jack, instead of the HDMI output (this can happen even if you don’t have an HDMI monitor plugged in).

To force audio through local 3.5 mm jack, open Terminal, and type

sudo raspi-config

What does the ssl.cnf file look like?

Here's what the ssl.cnf file would look like, replacing country, state, locality with your respective info.

“Cannot connect to the Companion Service” errors

This could be because of one of 3 things -

1. Bad certificate - which could be a result of -

   • Bad ssl.cnf file (See FAQ above for what it should look like),
   • incorrect java version,
   • possibly wrong passphrase in the config.json file,

2. Incorrect Product id - Make sure that these values are the same -

   • Device Type Info -> Device Type ID on the Amazon Developer Portal, and
   • Product ID in SSL cert generation (when prompted by generate.sh), and
   • Product ID in config.json
   • the "key" in the products "key":["value"] pair in config.js, and

3. Incorrect DSN - Make sure that these values are the same -

   • dsn in config.json, and
   • the "value" in the products "key":["value"] pair in config.js

4. The Companion Service isn’t actually running.
