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 :doc:`/wireless/index` since it's a Bluetooth
HAL client, not part of the primary audio HAL.
