Assist with M5Stack: No audio confirmation

Configuration Voice Assistant
1

I’ve got some M5 Stacks working fine with Assist, I can turn off/on lights without any issues, but the device never plays back and confirmation audio

The ESPHome logs show

It looks like the audio starts/stops immediately and I can play the wav file without issues from the web browser

I’ve got no customization on the config file

substitutions:
  name: denm5stack
  friendly_name: Den Atom Echo
packages:
  m5stack.atom-echo-voice-assistant: github://esphome/firmware/voice-assistant/m5stack-atom-echo.yaml@main
esphome:

  name_add_mac_suffix: false

    key: kYYaz9V9MqR1MKs9HugqRDdVGjSd5QJTrnYR7xDnqis=

  password: !secret wifi_password

What have I missed?

After some updates via ESPHome, it seems like it’s working as expected now, I’m not really sure why it broke (the encryption key has changed since my original post)

Since this was the first post I saw when I saw “no audio” when searching. I found the fix for now which was just adding the following in your esp portion of the yaml. Hope this helps anyone else stressing out about getting it to compile.
