Ok, all work well... go to my "project.cpp":

    int main(int argc, char *argv[])

    {

        ECA_CONTROL_INTERFACE e;

        e.command("cs-add play_chainsetup");

        e.command("c-add 1st_chain");

        e.command("ai-add /home/pfructuoso/Musica/Musica_Tecno/BonGarcon.mp3");

        e.command("ao-add jack_auto,alsa_pcm");

        e.command("cs-select play_chainsetup");

        e.command("cs-connect");

        e.command("start");

        sleep(5);

        e.command("stop");

        e.command("cs-select play_chainsetup");

        e.command("cs-disconnect") 

        std::cout << "FIN" << std::endl;

        return(0);

    }

compile... all well... try execute it:

    # ECASOUND=ecasound

    # projecto 

    (ecasoundc_sa) Error='read() error', cmd='cs-disconnect' last_error='' cmd_cnt=9 last_cnt=8.

UPSSS!!! Something had happen... I can listen the music without problem. Try changing my code for:

        e.command("cs-select play_chainsetup");

        e.command("cs-connect");

        e.command("start");

        sleep(5);

        e.command("stop");

        e.command("cs-select play_chainsetup");

        //     e.command("cs-disconnect");

and all work well.
