Welcome to the community!
Since microphone and speaker testing is working, your MATRIX Voice should be fine.
The first screenshot you provided indicates services on the Snips side are not running properly, specifically snips-analytics in that image.
Are all the services running now if you type
sam service log into your computer’s terminal after connecting to the Raspberry Pi?
Regarding your second post, it seems the Snips weather demo is using Python 2.7 which will be deprecated soon, so the error is asking you to move away from Python 2.7. Here is a post on the Snips forum of someone trying to upgrade their Snips assistant to Python 3.
All that said, I have not received this error before, so I will try to replicate it and let you know if I can find out more.
Hope this helps!
