I recently switched to Linux, because, like, why not. Now I can’t use many GMod mods because they end up showing errors, and in the console, they show something like this:
Failed to load sound "vehicles\whyisthisnotworkingonlinux.wav", file probably missing from disk/repository
Note that this issue only appears to occur with vehicle mods and only Linux systems (I have tested Ubuntu 16.04, Ubuntu 14.04, and Debian 8, no rpm based distros yet though. On Windows, this issue does not occur, I haven’t yet tested on a Mac).
