As an emulator user, I want vemu's on-chip audio interfaces (I2S/SAI/PDM) to stream real sample buffers, so that MCU audio-driver firmware (EasyDMA handoff, start/stop, IRQ) runs and can be regression-tested without a physical codec.

Why it matters

Let MCU audio-driver firmware (EasyDMA buffer handoff, start/stop, IRQ) run without a real codec

Summary

On-chip audio interfaces (I2S/SAI/PDM)

Scope of work

Partially modeled. Complete the missing mechanics of On-chip audio peripherals (I2S/SAI/PDM). What it is: On-chip audio interfaces (I2S/SAI/PDM). Why it matters: Let MCU audio-driver firmware (EasyDMA buffer handoff, start/stop, IRQ) run without a real codec.

Current state

Status: Partially implemented. Notes / evidence: Nordic nRF I2S/PDM are functional EasyDMA models (TX consumed, RX filled with silence, events+IRQ+DPPI); ST SAI is a bare register stub; RK I2S/TDM + ST ADF present; no live sample content.
