This is happening to me, too. I think it is happening anytime I pull my cam back into my neighbor's parcel, but I'm not 100% certain.
I turned on beacons for sound and am pretty sure it is not an object. I think it must be the media stream. It's the first few bars of Auld Lang Syne, over and over and over again-- any time I zoom out to look at object placement it starts from the beginning again.
It's just dreadful.
Denrael, I'd love to know if you have made any progress.
