I got 2 and both sound exactly the same. You can see a video I posted a few posts up. Went to a neighbor friend and his sounds exactly the same as well. I only hear these sounds when I put my ears right next to it. Maybe people are talking about different sounds. Don't know.
My friend say he don't hear anything.... but i'm pretty sure he got it too. I retry this morning with complete silence in the house... this is way more irritating then i was expecting. I'm calling sony today no way i keep this... Someone can post a Ps5 that is quiet when playing AC or demon's souls please ?
