Almost every time I resume playback after pausing, there is a single, tiny pop mixed into the music a split second after resuming. It's not very loud, but definitely present. This originally happened over a Bluetooth speaker, but I just tested for it over wired headphones and got the same result.
Oddly and specifically enough, the glitch often sounds more like a pop when pausing/resuming using controls on the BT speaker/headphones, but sounds more like a tiny skip when using PA's own pause/resume button.
I never noticed this glitch before recently turning off "Beep" in PA's Bluetooth
