Linux version can't reproduce sound

[guihkx]

Simple macro to test:

macro(2000, "sound test", function()
  local result = playSound("/sounds/Player_Detected.ogg")
  print(result and "ok" or "fail")
end)

Console:

I'm using the last build downloaded from this repository (commit 9522f83), yet this is the build version shown in the Linux client:

Funnily enough, I can play the Windows version on Linux using Wine just fine, and the audio works too ¯\_(ツ)_/¯

Still, it'd be great to have audio working on the Linux version.

Thanks
