How To Play TTS from RaspberryPi 3.5mm audio jack?

I’m going crazy trying to setup sound output on Raspberry Pi.
I tried install VLC and Mopidy plugins (via custom repos) but I cannot hear any sound.
In addiction to this, by now I have Mopidy installed but even if I set

media_player:
    platform: mpd
    host: 127.0.0.1

it is not detected.
Can someone help me?

Setup:
Raspberry Pi 3
HassOS: 2021.1.0
