It only seems to happens with MW3 occasionally whilst playing online, the sound will go deafening loud and make a pulsating kind of tone, even if the tv speakers are set to a very low volume.
To cure it, it either goes away on it's own after about 30 seconds to a minute.
Or when it increases in volume I'm worried it will blow the tv speakers. So I switch my tv off and then on again, and the noise goes away.
So is my tv faulty, my ps3 faulty? the hdmi lead faulty? or simply a MW3 online error?
Doesn't happen with any other game offline or online which is strange.
So got a hunch it's probably a MW3 server error.
Anyone alse had this weird problem?
