Problem on Raspberry Pi 2B

[stefanofornari]

Hello, let me know if I should ask somewhere else... I run the script and all completed successfully. I have the following device connected:

However, I am not sure everything went well (and I can not hear the sound from the speaker).

pactl list cards (no card?)

In case anybody can help, I am available for any test/troubleshooting.
