Can you run a simple Lua script and try something like this:

res=os.execute('/usr/bin/sox --version')

Just to make absolutely certain that you are able to call sox from within a Lua script.

Having a spot of bother with this bit of lua:

result = os.execute(string.format([[sox --norm %s %s.new]],
file_to_normalise, file_to_normalise))

It's returning -1. I believe freeswitch is running as root and that the
sox file is in that location and is runnable.

Any ideas?
