Get the Audio Endpoint for the specified device index. Call repeatedly with index starting at 0 and increasing to get all available devices, including disabled and unplugged devices, until the false is returned. You can also get the default device information by specifying index=-1. The default device is the one with a green checkmark in the Audio Playback Device panel in Windows. The returned out_uDeviceID parameter is the Device ID to use with Wwise. Use it to specify the main device in AkPlatformInitSettings.idAudioDevice or in AK::SoundEngine::AddSecondaryOutput. The returned out_ppDevice is a pointer to a pointer variable to which the method writes the address of the IMMDevice. out_ppDevice is optional; if it is null, then no action is taken. If the method returns false, *out_ppDevice is null. If the method successed, *out_ppDevice will be a counted reference to the interface, and the caller is responsible for releasing the interface when it is no longer needed, by calling Release(), or encapsulating the device in a COM Smart Pointer.
