_HDAUDIO_DEVICE_INFORMATION_V2 structure

-description

The _HDAUDIO_DEVICE_INFORMATION_V2 structure specifies the hardware capabilities of the HD Audio bus controller.

-struct-fields

-field Size

Specifies the size in bytes of the _HDAUDIO_DEVICE_INFORMATION_V2 structure.

-field DeviceVersion

Specifies the HD Audio controller device version.

-field DriverVersion

Specifies the HD Audio bus driver version.

-field CodecsDetected

Specifies the number of codecs that the HD Audio controller detects on the HD Audio Link.

-field IsStripingSupported

Specifies whether the HD Audio controller supports Striping. If TRUE, it supports striping (with at least two SDO lines). If FALSE, it does not support striping.

-field CtrlRevision

HDA controller revision.

-field CtrlVendorId

HDA controller vendor ID.

-field CtrlDeviceId

HDA controller device ID.

-remarks

With the release of Windows 1903 the GetDeviceInformation method of all the HDAUDIO_BUS_INTERFACE* was expanded to also accept a larger input structure: _HDAUDIO_DEVICE_INFORMATION_V2. The original input structure of HDAUDIO_DEVICE_INFORMATION continues to be supported.

If the hdaudbus supports the new size, it inits all the fields and sets the Size field to sizeof(_HDAUDIO_DEVICE_INFORMATION_V2), else it returns the information only for _HDAUDIO_DEVICE_INFORMATION and sets the Size field to sizeof(_HDAUDIO_DEVICE_INFORMATION).

Usage Examples

_HDAUDIO_DEVICE_INFORMATION_V2 info;

_HDAUDIO_DEVICE_INFORMATION_V2_INIT(&info);

status = m_BusIntV3->GetDeviceInformation(m_BusIntV3->Context, (PHDAUDIO_DEVICE_INFORMATION)&info);

The GetDeviceInformation routine uses the _HDAUDIO_DEVICE_INFORMATION_V2 structure to provide information about the HD Audio controller's device-specific capabilities to clients.
