[UE-5] How do I capture audio from an Input and have it NOT routed to the main speakers?

Hello,

I am trying to capture audio from a microphone and use the audio to affect a Niagara object.

This works when I create the Niagara object and don’t select any sub mixes. It USED to work if I created a sub mix, selected the sub mix for audio spectrum and my audio capture blueprint, however, since UE5 released, this no longer seems to work.

Also, previously, when I selected a submix, I would route it to another sub mix and mute that submix… but that would cause the Niagara script to stop reacting to the audio.

No matter what, I see my audio envelope numbers bouncing around, so it seems like audio is coming in.

So, how do I capture audio, use it in a Niagara script and then NOT send that audio back out to the computer? Basically, I just want to capture the audio and not play it back. It seems sill that this is impossible to do.

Thanks!
