11. Audio

The audio DSP firmware (ADSP/CDSP Hexagon images, codec modules) and the audio-fabric kernel modules/HAL that drive it — by far the largest single driver/HAL group on this device (29 of 37 loadable kernel modules). Bluetooth audio, including a two-bug latency chain (one confirmed, one inferred), is documented in Wireless since it’s a Bluetooth HAL client, not part of the primary audio HAL.
