[question] how to remove speaker sound from microphone using pipewire, easyeffects, qpwgraph.

[malnaanah]

I am using Kubuntu 22.04, with pipewire, easyEffects, and qpwgraph.

I am trying to record from microphone and speakers simultaneously. Where the microphone audio is routed to easyEffects noise reduction filter. I can record the speaker without filtering by adding it to the easyEffects sink. The problem is that the speaker sound appears in the microphone, I want to remove the speaker sound from microphone input. Is there any configuration to do that. The attached image shows my configuration.
