The sound of a fireplace inside a house sometimes does not end, even when there is no longer fire going on.
It happened for me when I left the building when fire was still going on and came back when it was extinguished, but sound was still playing.
No idea if its tied to the fireplace proxy or the building, but it happened in the: land_house_2w02.
On the first image where I was standing it was still hearable and you can see that there was no longer fire.
On the second image "status" of the fireplace.
