Possibly related to this bug, ambient sound effects don't decrease in volume as you get further away, as long as you're still close enough to be able to hear them at all. This causes them to drown out other sounds in some cases. The beehive and the electric fence are two of the most noticeable examples. I'm not sure whether to open a separate ticket for this; I guess it's all part of the same code.

This has been fixed with the changes in pull request #568:

Many thanks to the original ZEngine developer, Anton Yarcev!
Closing as fixed
This seems to be a problem with how the universe_music script command is handled for ZGI (Nemesis doesn't use such functionality).
universe_music is supposed to set a sound that will only be used for a specific "universe" (world + room, I suppose?)
The script in question is dc10.scr
This does: action:universe_music:02310(0 dc10q01p.raw 1 100) # dc10_heart_sound action:pan_track:02311(02310 1110) # dc10_heart_sound
Upon exiting the scene, slot 2311 (the pan track) is killed, but slot 2310 (the heartbeat sound effect) is not killed, as it's a universal track. There's a check in the ActionMusic destructor:
ActionMusic::~ActionMusic() { if (!_universe) _engine->getScriptManager()->killSideFx(_slotKey); }
I'm not sure where track 2310 is supposed to stop. It should either stop when pan_track is killed, or when the room changes, or by game scripts. I can't find a game script that stops the sound itself, or all sounds of that type when exiting the castle.
This will need some checking with the original interpreter.
