My Question or Issue

Been using Spotify for some time, without any issues. Yesterday, on several devices, the volume will softly drop for less than a second, the back up. This goes on every 8-12 seconds (driving me nuts).

If I play on Samsung S8, no problem. If I play on S8 and cast to Denon AVR, or to Chromecast plugged into the Denon, problem occurs. Same problem on PC (Win10) when playing on PC or casting to Denon.

Suggestions?  Thank you.

Keeping a closer eye on this. Exactly 10 seconds between dropouts. 

Could it be something is making a zero second "announcement" that temporarily cause the volume to drop and then right backup again.

Anybody...help?

Finally found it: it was HDMI control on Denon receiver (connected to Sharp TV). I had enabled it for some unrelated reserch.
