My sound card is Yamaha Audiogram 6. When I plug it in my pc, I always hear the raw sound coming from it through my headphones. However, while I'm recording my FX added electric guitar on Studio One, the raw sound coming from the sound card gets mixed with the FX added sound on Studio One. The sound card doesn't have a "mute monitoring" button as far as I can see. How can mute the sound card and only monitor the FXed channel on Studio One? (I'm a Win10 user.)
