So I’m hearing it when it goes from a program to a commercial and vice versa. But it’s not every program to commercial or vice versa. It also just happened going from one commercial to the next. And I can rewind to the point I hear it and duplicate the noise every time.
And that clip from @doubleTap is the same sound I’m hearing. That is mid-commercial though.
I wish I could see what’s going on behind the scenes of the affected commercials to tell the difference for you.
