odas: Socket error: "Sink pots: Cannot connect to server"

Hello, I’ve been working with odas_ros and the 16SoundsUSB card. It is plugged in my computer and I ran the odas ros package.

The part of the configuration that is most interesting for this issue is:

potential: {

    format = "json";

    interface: {
        type = "socket";
        ip = "127.0.0.1";
        port = 9001;
    };

    #format = "undefined";

    #interface: {
    #   type = "blackhole";
    #};

};

When running the node that launches Odas I get the following error: Sink pots: Cannot connect to server That certainly means that the card cannot acces the socket at IP 127.0.0.1:9001. I’m not experienced with networks so I don’t know how to fix this issue. Any help would be welcome.

Many thanks

Ludovic

EDIT: I also have a doubt on this part of the configuration file: `raw: {

fS = 16000;
hopSize = 512;
nBits = 32;
nChannels = 16; 

# Input with raw signal from microphones
interface: {
    type = "soundcard";
    card = 1;
    device = 0;
}

}`

I found the card and device number with arecord -l
