Kerbal Space Program

Platform: Mac
Issue: sounds defined on parts that are in the ksp/sounds folder don't play on mac. Must be in the parts own folder.
To reproduce: Define an effect sound as described below, or try the firespitter mods propeller engines.
Probable cause: Sounds are pulled from the wrong folder on mac
Versions: At least 0.18 to 0.19.1

In my firespitter mod I have custom engine sounds defined for propeller engines. I have gotten several reports from Mac users about the sounds not working.
I didn't know if it was an issue with the sound files themselves, or a scripting error in the official code. Turns out it was the latter, as one of the users found a workaround.

The sounds are defined:

// --- Sound FX definition ---

sound_fsmustangstart.wav = engage
sound_fsmustang.wav = power
sound_explosion_low = flameout

the engage and power sounds are placed in the ksp/sounds folder. but unlike the flameout sound, which is an official sound, and probably handled differently, they do not play.

The workaround is to place the sounds inside a sounds folder in the part folder for each part. Seems there is an issue with how you handle file paths in the cfg parser or sound loading code.

If you want to test this bug on your own, the firespitter mod is on spaceport. Try any of the engines.
I don't have a mac myself, but I can confirm it works fine on linux and windows.
