I opened in RB all the WAV files of the "silent" tracks, and all, as you can see from the attached images, showed their correct signals in the waveforms and by playing in RB I listened to the song as it was in BIAB

The problem is this: If I open a WAV track exported by BIAB directly with VLC player (I checked the VLC output device that is correct on ASIO) I do not feel absolutely NOTHING
