Some game sounds not playing

[Caffeine]

Something to do with ffmpeg? I know I have it installed because I remember installing it when I updated Audacity some time ago.

Very unlikely ffmpeg has anything to do, as I doubt the game even checks any environment variables related to ffmpeg as it's older than ffmpeg, I believe it uses some proprietary libraries (as the logs suggest, one called Wavlib, part of DAlibs) to decode mp3.

Code:

C:\work\builds\dalibs\dalibs-build\build\Src\WavLib\wavlib.cpp(32) : ERROR:General:StreamingSound: missing MP3 codec?

I have the exact same warning spammed on my logs as well, but the sound still works fine, I'm playing this game through Wine, though. I think your best bet here is to ask @Aingar or wait for his input, as he's more familiar with the inner workings of the game engine.

These lines though seem to point to the root cause of the problem, which is some library called SoundStreamer, and unlike with the missing MP3 codec line I do not have these logged anywhere:

Code:
