Whats wrong with your ps3 when you play a game and sometimes the sound from the game doesnt play, online it doesnt load the maps right away
If you cannot hear the sound of the PS3 when playing the game, check the TV connections to ensure that they are in the right place. You can also use the manual to ensure that the connection is well mapped.
I've had my PS3 for 3 years and it hasn't had any of those problems. The sound may be caused by your TV but I'm not sure about the map loading.
