I couldn't get sound on "Audio Output Capture" channel.

I have created "Audio Output Capture", but there is silence on the channel. It is possible to listen to the microphone or video intro with sound separately, but it is impossible to hear together in the output channel. Tell me why?
Создаю "Захват выходного аудиопотока", но на канале тишина. Можно прослушать отдельно микрофон или видеозаставку со звуком, но вместе услышать в выходном канале невозможно. Подскажите почему?
