Post script you are using to call Csound api, might help.
require "luaCsnd6"
local c = luaCsnd6.Csound() -- Create an instance of the Csound object
c:Compile('test1.csd') -- Compile a pre-defined test1.csd file
c:Perform() -- This call runs Csound to completion
c:Stop() -- At this point, Csound is already stopped, but this call is here
-- as it is something that you would generally call in real-world
-- contexts
