Hello, list

I have this lua script, i try to put music to the aleg while do another task, but it is not working (not audio at all), any advice on what am doing wrong?

THanks in advance, here my script:

----------------------------------------------------------------------------------------------

require 'socket'
local host = "127.0.0.1"
local port = 8021

function set_hold(uuid)
    local conn = socket.connect(host, port)

    if (conn) then
        local cmd = "bgapi uuid_broadcast " .. uuid .. " /opt/freeswitch/sounds/es/dm/dm-promo-recharge-hold.G729 aleg";
        freeswitch.consoleLog("info", "CMD: " .. cmd .. "\n")
        conn:send(string.format("auth ClueCon\r\n\r\n%s\r\n\r\nexit\r\n\r\n", cmd))
        line, err = conn:receive()
        while (not err) do
            if (line ~= nil) then freeswitch.consoleLog("info", "SCKT: " .. line .. "\n") end
            line, err = conn:receive()
        end
        conn:close()
    else
        debug.notice("Error posting to server: " .. host .. ":" .. port)
    end
end

function sleep(n)
   os.execute("sleep " .. tonumber(n))
end

session:answer()
session:sleep(500);
uuid = session:get_uuid();
freeswitch.consoleLog("info", "UUID: " .. uuid .. "\n");

api = freeswitch.API();

set_hold(uuid);
freeswitch.consoleLog("info", " - - - RETURNED - - -\n");

for i=1,50 do
    if not session:ready() then break end
    sleep(1);
end

if session:ready() then api:executeString("uuid_break" .. uuid); end
freeswitch.consoleLog("info", " - - - FINNISH COUNTING - - -\n");

session:hangup();
