A call to the function AK::SoundEngine::AddOutput was made by the game code and it tries to add an audio output that is already present in the system. This is not a fatal error. The existing output will continue to work normally.
推奨される解決策:
Remove the function call.
Reevaluate the parameters in_settings.audioDeviceShareset and in_settings.idDevice to point to a different physical device.
