Plays quiet music when you have;
- An anesthetic mask on your face.
- Been put into a cryopod
- Been put into a sleeper
TBD: Maybe make sleeping do it, but iirc even dying does sleep.
There is a pref toggle for these under Preferences: "Sleeping Music"
Example [here](https://streamable.com/pls63y) of surgery being done. Volume is higher than normal, was adjusted down to 40%.
Preferences can now take a list instead of a singular datum (but will still accept a singular datum for legacy compat), and any arguments that check is_preference_enabled must return true on all prefs from the list, not just one.
Self-explanatory.
Adds toggle to go back to the old-school SS13 legacy airlock sounds, including the glass windoor airlock sounds, and a toggle to disable the per-department door sounds, which some found jarring/unrealistic.
If Per-Department sounds are disabled, the department doors will use hall1o/c for open/close respectively, following maintainer-requested behavior for these doors.
This also relocates the following sounds to be inside machines/door for more consistency:
- airlock.ogg
- airlockclose.ogg
- airlockforced.ogg
- airlock_creaking.ogg
- boltsup.ogg
- boltsdown.ogg
- blastdoorclose.ogg
- blastdooropen.ogg
- windowdoor.ogg
Adds a Random Ambience Frequency and Ambience Chance Setting under Global, underneath Client FPS. Images here:



Self-explanatory. Random-Ambience-Frequency controls how long before it checks if it can play ambience to you again. Setting it to 0 disables the random re-play of ambience.
Ambience Chance affects the % chance to play ambience to your client. It defaults to 35%, but can be set from 0 to 100 to disable it or always play every time you move into an area or have the Random Ambience check called.
