i see (hear) the same thing happening. I also think it's happening when switching to outside view, which i frequently do in pushback for instance, because it looks cool 😄 . if i do so , cabin calls are interrupted and then disappear entirely for the duration of the flight. I tried a short flight without ever going to outside view and had cabin calls from start to end. if i only go to outside view once, cabin calls are not present anymore, naturally with PA and CAB on and set to full audio volume.
