I’m long time Audacity user with a new version (3.6.1) on new MacBook Pro
I open a WAV file and edit. I place the cursor and PLAY; there is a short face it fade-in, which is unwanted.
If I stop and immediately hit PLAY again, there is no fade in, it is a sharp playback as expected. This works repeatedly if I am quick to rePlay.
If I STOP and wait a few seconds and hit PLAY, the fade in recurs.
I’ve noticed fade-ins when using headphones connected to a USB interface. I have to plug the headphones into the headphone jack of the sound card to avoid it.
