Compressor expander not working ?

[Npa972]

Hi , How to reproduce : listen for example to Ravel's bolero which starts so low that you can barely hear the music. I tried playing with the compander settings and I don't hear any change. Audacious for example has an audio compressor effect and a background music effect whitch both work very well on the aforementioned track. Maybe i missed something ? I really like the Jamesdsp equalizer. Thanks ! OS : arch Sound pipewire music player : rhythmbox jamesdsp-git
