I’m using SAB version 9.2.4, Feb 22, 2022 and fine tuning Joshua 1, 2. I’m using a Logitech USB headphones. My mp3 files are clean but after doing Syncronizing with aeneas and then doing fine tuning I can hear a tapping sound in the audio while doing the fine tuning (almost once every second). The Joshua mp3 files don’t have this tapping sound. What must I do to get rid of it?
