Public Methods

::fidl::internal::WireBufferThenable< ::fuchsia_hardware_audio::StreamConfig::GetHealthState> GetHealthState ()

Retrieves top level health state.

A driver not responding promptly can be used as an indication of an unhealthy driver.

Caller provides the backing storage for FIDL message.

::fidl::internal::WireBufferThenable< ::fuchsia_hardware_audio::StreamConfig::GetProperties> GetProperties ()

Retrieves top level static properties.

Caller provides the backing storage for FIDL message.

::fidl::internal::WireBufferThenable< ::fuchsia_hardware_audio::StreamConfig::GetSupportedFormats> GetSupportedFormats ()

Gets formats supported by a given driver. When not all combinations supported by the

driver can be described with one `SupportedFormats`, the driver returns more than one

`SupportedFormats` in the returned vector. For example, if one `SupportedFormats` allows

for 32 bits samples at 48KHz, and 16 bits samples at 96KHz, but not 32 bits samples at

96KHz, then the driver replies with 2 `SupportedFormats`:

<

<

32bits>,

<

48KHz>> and

<

<

16bits>,

<

96KHz>>. For simplicity, this example ignores parameters other than rate and

bits per sample. In the case where the driver supports either 16 or 32 bits samples at

either 48 or 96KHz, the driver would reply with 1 `SupportedFormats`:

<

<

16bits,32bits>,

<

48KHz,96KHz>>.

::fidl::internal::WireBufferThenable< ::fuchsia_hardware_audio::StreamConfig::WatchGainState> WatchGainState ()

Get the gain state via a hanging get. The driver will reply to the first `WatchGainState`

sent by the client and this reply must include a `gain_db` set to 0dB or lower. The driver

will not respond to subsequent client `WatchGainState` calls until the gain state changes

from what was most recently reported.

If `WatchGainState` is called for a second time before the first call has completed, then

the protocol channel must be closed with the error `ZX_ERR_BAD_STATE`.

::fidl::internal::WireBufferThenable< ::fuchsia_hardware_audio::StreamConfig::WatchPlugState> WatchPlugState ()

Get the plug detect state via a hanging get. The driver will reply to the first

`WatchPlugState` sent by the client. The driver will not respond to subsequent client

`WatchPlugState` calls until the plug state changes from what was most recently reported.

If `WatchPlugState` is called for a second time before the first call has completed, then

the protocol channel must be closed with the error `ZX_ERR_BAD_STATE`.
