I noticed whenever you unsuccessfully recontain SCP-106, he'll suddenly come walking through the window. That may be my bad, but if you fall in the pocket dimension with the Sound Transmission switch turned On, then it will keep playing in the Pocket Dimension and in any other place.

While it can be fixed by a restart, it's very annoying to restart the game, especially at a Keter level game mode.

Yeah, I noticed this a while back and it's extremely annoying. I think it's a bug? Well it's gotta be if you can hear it in the pocket dimension, that's not even reality for cryin out loud....or is it?

Update: I noticed a restart doesn't help, and starting a new game still contains the noise. However, teleporting to SCP-106's chamber helps.

Not that it's useful or anything -__-
