nDeviceIndex |
Number representing the zero-based index of the ASIO device. This index is related to available ASIO devices so it must be the related to the enumeration performed through the ASIO.DeviceGetCount and ASIO.DeviceGetDesc methods: it must not be confused with indexes related to generic input devices enumerated through the GetInputDevicesCount and GetInputDeviceDesc methods which may contain both DirectSound and ASIO devices. |
