pawn Код:

stock PlayAudioStreamForAll(url[])
{
    for(new i; i<MAX_PLAYERS i++)
    {
        if(IsPlayerConnected( i ))
        {
            
            PlayAudioStreamForPlayer(i, url); //removed x,y,z and distance since you won't need that there
        }
    }
    return 1;

}

Copy paste the code above over your old stock, I fixed the first error there.
Now, all you have to do is this:

pawn Код:

if(response)
        {
            PlayAudioStreamForAll(inputtext);//changed the non-existing 'url' to inputtext
        }

This should do the trick.
