No custom sound files are played, but in-game sound files are played. Sound file has 44100Hz I have tried stereo and mono mp3 and ogg I have also tried
local soundFile = "addons/testaddon/sound/testsound.wav"
hook.Add("KeyPress", "myTestAddon", function(ply, key)
if key == IN_JUMP then
sound.Play(soundFile, ply:GetPos(), 75, 100, 1)
print("Test")
end
end)
