- old optimization bypassed audio-stream resampler (16k direct -> MCLK 4.096MHz vs 11.29MHz native) - brick game correct because it used audio_stream path - now MCP uses audio_stream_open_output/input + read/write matching native logger stack - falls back to direct I2S only if audio-stream device missing
