From the save game, move right to another screen (do that back and forth) to hear a really laud crackling on start of the new ambient music piece.

This happens all over the game, whenever there is another music started, the crackling can be heard first.

Reproduced on 2.6.0 (Windows x64) and the US Steam version of the game. I don't know I would describe it as a "really loud crackling", but there is definitely a "thump" sound, almost like someone tapping on a microphone. It's not particularly loud and had I not been looking for it, I probably would have ignored it.

An even easier method to reproduce

• load the savegame
• click on the "computer" bubble (in-game save/load)
• click on "Cancel" (return arrow)

Everytime you get back into the game, the main theme of the scene will be load and an audible "thud" can be heard.

You can also swim to the left and back to the right from the save game (two different music pieces)
The "crackling" became a loud "thud" (@Thunderforge) in the meantime for me as well.
But it "is" really audible.

Could the music data been read from position -1 instead of 0, maybe (regression)?
