Have it run on your onplayerconnect callback

Код:

public OnPlayerConnect(playerid)
{
    PlayAudioStreamForPlayer(playerid, "audiourl", 0, 0, 0, 50, 0);
    return 1;
}

Then use

for when the player spawns.

Код:

public OnPlayerSpawn(playerid)
{
    StopAudioStreamForPlayer(playerid);
    return 1;
}
