Sony srs-xb43 paired with Chromecast

[Someguy2]

I got the Sony srs-xb43 a few days ago, and since then, every time I am pausing/playing an episode of a series on Netflix, Prime Video, or watching a video on YouTube or just navigating through apps and settings on my chromecast, it is just lowering the volume by itself.

Is there any solution to this problem ?

Thanks.

Does it happen with different devices as well? Or with the Chromecast only?

If it happens with the Chromecast only, does it happen with certain apps?
