What it does
deki-audio exposes audio output as a scene component. The engine core defines IDekiAudio; this module ships the MAX98357Audio component that drives the MAX98357 class-D mono amplifier over I²S.
Configure the I²S bus through deki-i2s, place the audio component in the prefab, and play PCM data from any behaviour.
Adding a different audio backend
Implement IDekiAudio for the new chip’s protocol and wrap it in a component. No core changes.
