Play Audio instead of TTS

This is my code:

#!/usr/bin/env python3
import sys
import json
import os

data = json.loads(
intent = data["intent"]["name"]
wake = data["wakeword_id"]

if wake:

if intent == "hello":
    os.system("aplay /home/pi/Desktop/0.mp3")

I see that Rhasspy TTS has the option of Local Command, but, do not use it (I do not see any example and I’m a little lost), so I think the most feasible thing is to do it directly on the Python code, or I’m wrong?

The code that I have reproduces the audio from console, but, not in

Some help?
