When I switch radio stations, and during the first sentence of dialogue (not music), one single word will repeat. Intermittent, maybe once every few days it happens. It is so subtle that I was not even be sure that it was actually happening, or just imagining it. Now it's happened five or 10 times and its definitely happening. Not a problem at all, just strange. Of course these audio systems have memory, and for some reason it's buffering one word and repeating it. Am I the only one who's noticed this? I'm sync 3 with 2.2 installed.
