Info - Element
DaiFormat Set - This table represents the possible Dai formats that this endpoint can support.
- Element
Ring Buffer Format Set - This table represents the possible RingBuffer formats that this endpoint can support.
- Info
- When a device is detected (or added via
Provider/AddDevice), it is queried for its properties and capabilities. Once this enumeration process completes, it is announced to clients that are watching for device arrivals viaRegistry/WatchDevicesAdded. - Observer
Watch Plug State Response - PcmFormat
Set - This table contains vectors representing three dimensions of device configuration (channelization, sample format, frame rate). The device should support all combinations of the items in these vectors.

Constants§
- DEFAULT_
DAI_ INTERCONNECT_ ELEMENT_ ID - For devices with Codec drivers, there is only one DAI_INTERCONNECT entity. When a method requires us to address the interconnect by ID, we use element_id 1. Codec drivers that implement signalprocessing should not assign this ID to other elements.
- MAX_
COUNT_ CHANNELS - Maximum number of channels that a device can report as supported.
- MAX_
COUNT_ CHANNEL_ SETS - Maximum number of
ChannelSets that a device can report in a single PcmFormatSet. - MAX_
COUNT_ DAI_ FORMATS - MAX_
COUNT_ DEVICES - Maximum number of audio devices in the system at any time.
- MAX_
COUNT_ FORMATS - Maximum number of
PcmFormatSets that a device can report as supported. - MAX_
COUNT_ PROCESSING_ ELEMENTS - Maximum number of processing elements supported by a single device.
- MAX_
COUNT_ RATES - Maximum number of frame rates that a device can report in a PcmFormatSet.
- MAX_
COUNT_ SAMPLE_ TYPES - Maximum number of distinct sample formats that a single PcmFormatSet can contain.
- MAX_
STRING_ SIZE - Maximum length of the strings for device, manufacturer and product names.
- UNIQUE_
INSTANCE_ ID_ SIZE - The length of the device’s unique ID, in bytes.
Type Aliases§
- Clock
Domain - Common aliases, consts and types used by more than one of the fuchsia.audio.device protocols.
- Element
Id - TokenId
