Common Pitfalls & Tuning Tips

• Clock mismatch between host and BR21 causes pops/clicks — ensure proper PLL/clock config and master/slave DAI mode.
• Incomplete power sequencing can brick peripherals — follow recommended regulator enable order.
• Improper buffer sizes or DMA configuration leads to underruns/overruns; match DMA burst sizes to audio frame sizes.
• Default firmware parameters may be conservative; tune AEC/NS settings using in-field audio captures.
• Monitor thermal and CPU usage when enabling heavy DSP features (ANC, voice pipeline).
