[Afterburner] Hemorrhoids with Audio Source 2

Hello. The problem is, audio source # 2 in msi afterburner video capture program does not work. If you put the audio capture from the microphone in the first place, and the audio capture from the PC to the second, then there will be no sound from the PC (from the game, but it will be from the microphone), if vice versa, that is, # 1 sound from the PC (games), # 2 microphone, then there will be no sound from the microphone, but it will be from the pc. Something incomprehensible with this audio source # 2, tried all possible options in the settings, to no avail.

Who had it and how to decide? Thank you.
