Hi,
I just reconfigured a m5stack Atom with the default “Media Player” template from the official webpage: Ready-Made Projects — ESPHome (Media Player > m5 stack)
Setup is OK (despite the compilation warnings wrt deprecated fastLED components –I got rid of the warnings by replacing the “light” section, cf. below)
Anyway, I can’t get any sound played out of the Echo device… only got instead some kind of white noise, letting me suspect that the sound can’t be properly decoded or sthg??
Eventually, i am loading this config on the Atom device:
substitutions:

friendly_name: M5Stack Atom Speaker Kit b87824

When pressing the onboard button:
- ‘media_player.ipad’ is properly playing the "this is a test’ sentence (so no issue with DNS routing, etc…)
- but no sound on the Atom Echo device (or rather: some white/noisy sound)
Also: trying to play a wave file directly from HA service (developer tools > Services), give me the same outcome:
- ok on the ipad
- nok on the Atom device

my conclusion: mp3 format/codec can’t be the root cause.
Since I am pretty sure it was working fine “before” (well, actually: quote: "it’s playin’! " 
), are you guys aware of any recent changes in ESP IDF / Arduino / ESP Home, about this? and is there a mitigation already ?
