To hide the Audio Steam : Link message there are only one solution that we send the player empty client messages which will clear his chat in random amount of seconds he won't be able to see any stuff above

pawn Код:

PlayAudioStreamForPlayer( playerid, "your link here!");
for(new i = 0; i < 50; i++) SendClientMessage(playerid,-1," ");//that line will clear the player chat by sending empty client messages!

Also you said that when the player enter the vehicle it send the client message to all the players , that's wrong it only send for the player who entered the vehicle 'if you didn't create a loop through all players with player the audio streamer for all ' , could you show me the codes that play the audio streamer when the player enter a vehicle ?
