Remarks

 

Given the zero-index of a generic input device, obtains the zero-based index of the corresponding ASIO device inside the list of available ASIO devices.

 

The list of generic input devices, which may include both DirectSound and ASIO devices, can be enumerated through the GetInputDevicesCount and GetInputDeviceDesc methods. The list of ASIO devices, which includes ASIO devices only, can be enumerated through the ASIO.DeviceGetCount and ASIO.DeviceGetDesc methods.

 

When the InitDriversType method has been called with the nDriverType parameter set to DRIVER_TYPE_ASIO or DRIVER_TYPE_BOTH_ASIO_FIRST, indexes of generic input devices will always match indexes of ASIO devices so the use of this method could be avoided.

 

When the InitDriversType method has been called with the nDriverType parameter set to DRIVER_TYPE_BOTH_DS_FIRST, DirectSound input devices will be listed first inside the list of available generic input devices so indexes of generic input devices will not match indexes of ASIO devices: in this case this specific method allows matching a generic input device to a specific ASIO device.

 

If you know the zero-based index of an ASIO device inside the list of available ASIO devices and you need to know its zero-based index inside the list of generic input devices, you can use the ASIO.DeviceGetOutputIndex method.

 

For further details about the use of ASIO drivers see the ASIO object section and the How to manage ASIO drivers tutorial.
