Improve audio host stream event reporting

2026-08-27T13:28:07Z

Report asynchronous start and stop completion with transfer results. Replace the ambiguous stream error callback and byte count with explicit transfer-failure events, and ignore stale completions after stopping.

audio: correct host API documentation

2026-08-27T08:34:34Z

Describe configuration limits by their actual storage scope, document asynchronous stream startup and shutdown, clarify that FIFO APIs are always non-blocking, and correct playback callback ordering. Signed-off-by: HiFiPHile

audio: expose generic Audio Control requests

2026-08-27T08:34:34Z

Remove the narrow public Feature Unit request API while retaining managed mute and volume helpers. Expose validated Audio Control descriptors during enumeration and provide raw asynchronous and synchronous entity requests for advanced controls. Signed-off-by: HiFiPHile

audio: normalize Feature Unit volume requests

2026-08-27T08:34:34Z

Accept the defined silence value and round ordinary volume requests to the nearest supported resolution step within the cached range. Add tests for silence, clamping, and step alignment. Signed-off-by: HiFiPHile

audio: add UAC2 host streaming support

2026-08-27T08:34:33Z

Add protocol-selectable UAC1/UAC2 parsing, UAC2 terminal and Feature Unit topology, Clock Source discovery, sampling-frequency ranges, and protocol-specific stream controls. Cover UAC2 playback, capture, control discovery, and malformed descriptors with unit tests. Signed-off-by: HiFiPHile

audio: compact alternate-setting storage

2026-08-27T08:34:32Z

Store each Audio Streaming alternate setting once and flatten its sample rates only at the public API boundary. Keep feedback and pacing state playback-only, eliminating duplicate configuration fields from capture streams. Signed-off-by: HiFiPHile

feat(audio): discover stream mute and volume controls

2026-08-25T07:29:08Z

Inspect each associated Feature Unit during mount, cache master mute support and the common MIN, MAX, and RES volume range, and ignore units with neither control. Add typed asynchronous and synchronous mute and volume APIs and demonstrate them in the host example. Signed-off-by: HiFiPHile

fix(audio): keep stream state consistent on control failures

2026-08-25T07:29:07Z

Route asynchronous activation and sampling-frequency failures through the stream error callback. Keep a running stream active when SET_INTERFACE alt 0 cannot be submitted so stop can be retried without diverging from device state. Signed-off-by: HiFiPHile
