Anything's possible. I'm using a laptop with a realtek sound card. I normally have it playing through bluetooth speakers, but it happens when it isn't.

It can happen on any song of a sequence. So during a session, it doesn't happen on every song and it doesn't necessarily happen on the first song or on a song after a long pause of playing nothing. So if it is some sort of "noise gate" it doesn't seem to trigger in any consistent manner. I'm struggling to find any pattern to it. It has been happening for years, possibly on the machine that the current laptop replaced. It's been annoying, but never quite annoying enough to report until now.
