Confirmed this works on the Muse proto using

external_components:
  - source: github://pr#3568
    components: [i2s_audio]
    refresh: 0s

Without this PR there is no sound after a power cycle

Thanks for confirming @Jason-nz

Does your proto onboard speaker emit sound ? (I can hear the speaker emiting a small noise at volume 0 like every speaker "skrch skrch") or do you use an external speaker ?

[Jason-nz]

I have 2, one arrived without the onboard speaker working, the other works as expected.
Have you tried an external speaker?

From what I can tell, the onboard speaker is hard wired and can only be disabled by cutting a trace on the back. So if you have sound with an external speaker then you might have a faulty onboard speaker.
