Data:

AUDIO_DEVICE_PROPERTY_NUM_OUT_CHANNELS: The number of output channels supported; of type int.

AUDIO_DEVICE_PROPERTY_NUM_IN_CHANNELS: The number of input channels supported; of type int.

AUDIO_DEVICE_PROPERTY_CHANNEL_ORDER: The output channels, listed in setup order; of type audio_manager_channel_t[].; This parameter is only permitted if AUDIO_DEVICE_PROPERTY_NUM_OUT_CHANNELS is requested as well. If the number of channels is greater than the input value for AUDIO_DEVICE_PROPERTY_NUM_OUT_CHANNELS then, at most, the input value will be written.

AUDIO_DEVICE_PROPERTY_CHANNEL_CONFIG: The audio device configuration of the audio device; of type audio_manager_channel_config_t.; The value may be multiple values from this enum OR'ed together.

AUDIO_DEVICE_PROPERTY_SUPPORTED: Whether the device is supported on this platform; of type bool.

AUDIO_DEVICE_PROPERTY_CONNECTED: Whether the device is currently connected; of type bool.; For example, in the case of headphones, indicates whether the headphones are plugged in.

AUDIO_DEVICE_PROPERTY_SUSPENDED: Whether the device is suspended; of type bool.

AUDIO_DEVICE_PROPERTY_VOLUME_CONTROL: The type of volume control supported by the device; of type audio_manager_device_volume_control_t.

AUDIO_DEVICE_PROPERTY_PUBLIC: Whether the device is public; of type bool.; This means a device may be listened to by multiple listeners, such as a speaker, as opposed to a private device listened to by one person, such as headphones.

AUDIO_DEVICE_PROPERTY_NUM_HW_IN_CHANNELS: The number of input channels supported by the device.; This enumerator represents the true number of input channels that a device supports and therefore differs from the AUDIO_DEVICE_PROPERTY_NUM_IN_CHANNELS enumerator.

AUDIO_DEVICE_PROPERTY_COUNT: The total number of device properties supported.
