As Frans says, we've heard nothing. I just put up with it tho it doesn't often cause a problem, mainly because in my household the volume levels are often below that which causes the problem. I've got 2-3 4k blurays that do this so most don't. I'm expecting Oppenheimer to do it when I watch it. Never happens with the Sky Q Box or Firestick as source. I like the DSW and that it matches my M system and can't afford to change either!
I do wish M would at least reply to us though.
