Public Methods
::fidl::internal::NaturalThenable< ::fuchsia_hardware_audio::Dai::GetHealthState> GetHealthState ()Retrieves top level health state.
A driver not responding promptly can be used as an indication of an unhealthy driver.
::fidl::internal::NaturalThenable< ::fuchsia_hardware_audio::Dai::Reset> Reset ()Resets the DAI HW. The `ring_buffer` channel obtained via `CreateRingBuffer` may be closed
by the driver, in this case the client needs to obtain a new `ring_buffer`.
`Reset` returns when the reset is completed. If the driver can't successfully reset the HW,
it will close the DAI protocol channel, in this case the client may obtain a new DAI
protocol channel and retry.
::fidl::internal::NaturalThenable< ::fuchsia_hardware_audio::Dai::GetProperties> GetProperties ()Retrieves top level static properties.
::fidl::internal::NaturalThenable< ::fuchsia_hardware_audio::Dai::GetDaiFormats> GetDaiFormats ()Retrieves the DAI formats supported by the DAI, if not available at the time the DAI
may reply with an error status and the client may retry at a later time.
Retrieving multiple `DaiSupportedFormats` allows for cases where exclusive combinations of
the parameters in SupportedFormats may be supported.
::fidl::internal::NaturalThenable< ::fuchsia_hardware_audio::Dai::GetRingBufferFormats> GetRingBufferFormats ()Retrieves the ring buffer formats supported by the DAI, if not available at the time the DAI
may reply with an error status and the client may retry at a later time.
Retrieving multiple `SupportedFormats` allows for cases where exclusive combinations of
the parameters in `SupportedFormats` may be supported.
::fit::result< ::fidl::OneWayError> SignalProcessingConnect (::fidl::Request< ::fuchsia_hardware_audio::Dai::SignalProcessingConnect> request)Connect to a `SignalProcessing` protocol.
Multiple connections may be supported, if a new connection request is not supported, i.e.
the maximum number of connections have already been created, for instance one, then the
`protocol` channel (not the channel upon which `SignalProcessingConnect` is being called)
will be closed with a `ZX_ERR_ALREADY_BOUND` epitaph.
If signal processing is not supported at all, then the `protocol` channel (again, not the
channel upon which `SignalProcessingConnect` is being called) will be closed with a
`ZX_ERR_NOT_SUPPORTED` epitaph.
This method is named `SignalProcessingConnect` instead of `Connect` because this protocol
is intended to be composed, and hence the more verbose name allows differentiation and
improved clarity.
::fit::result< ::fidl::OneWayError> CreateRingBuffer (::fidl::Request< ::fuchsia_hardware_audio::Dai::CreateRingBuffer> request)`CreateRingBuffer` is sent by clients to select both a DAI format and a ring buffer format
based on information that the driver provides in `GetDaiFormats` and `GetRingBufferFormats`,
what is supported by the client, and any other requirement. The `ring_buffer` channel is
used to control the audio buffer, if a previous ring buffer channel had been established and
was still active, the driver must close that (ring buffer) channel and make every attempt to
gracefully quiesce any on-going streaming operations in the process.
