steam – why wont my Soundscripts work on portal 2’s workshop it doesn’t matter what I’ve tried?

in a number of portal 2 maps I just lately printed to steam workshop, folks have been complaining fairly persistently about lacking soundscripts. (made apparent by the out-of-place hl2 voice line used for the error sound within the engine)

I’ve tried every part I can consider to make it work nevertheless it simply wont.

this is what I’ve tried:

• bspzipping the soundscript into the map together with a modified manifest together with it
• bspzipping simply the manifest
• bspzipping a per-map _level_sounds.txt
• enjoying the .wav instantly somewhat than use a sound script (works however not viable as a consequence of much less options accessible this manner)
• …and all permutations and combos of all 3 of these information being bspzipped or not
• operating sv_soundemitter_flush by way of a logic_auto and point_servercommand within the map on map spawn
• screaming at it

much more maddening is it really works nice on my finish virtually each dang time however merely wont work in any respect on the steam workshop which is senseless in any respect given my file system setup, which is designed by me to particularly by no means mount something except for portal 2’s vanilla information. if it really works in my native model, it ought to work within the workshop model. so I do not perceive what breaks through the add.
