I’ll do my best! 
When you install VoiceMeeter, it will control all audio going in and out of the system; all outputs from all player apps MUST connect to FxSound’s input, FxSound’s output MUST be connected to VoiceMeeter’s VAIO input. A1 and A2 are outputs for your audio hardware (sound cards, etc.) B1 and B2 are virtual outputs for audio recording apps or virtual audio cables (VB-Audio has a free one, check it out) for special applications. When I said “Connect media player to FxSound”, I meant software media players, sorry about that!
