This happened right before the match that erased my games and Game Data Utility folder contents and I got the error 'Client Command Overflow' screen ???

Everyone that runs into this issue needs to contact activision support and create a support ticket, the developers nor support come here and read the topics, this issue effects 3 games in the series (that i know of, mw2, black ops, and mw3, i only know of those 3 because my first cod game was mw2),

Get in contact with activision support for them to realise that this is not a isolated issue, they are seeing it as a isolated issue because you all are only posting about it on the forums and not taking it to support.

Again everyone that has posted here needs to also report it to support or this issue will not get resolved if you don't. 

That audio EMP is the worse. I got a pair of Trittons that are usually turned up loud because I am hard of hearing (damn 80's metal) but when that buzz goes, I have to throw my headset off in fear of my ears bleeding.

I think it's a conspiracy, a subliminal message that all the sudden get's audible. It's the worse.

I've had this noise as well, shat my nappy when it happened!

WOW!!!  Someone else on a right track... but Vern they say; how can they hack using just the audio lines???  Well, I thought thats what them guys got their fancy degrees to figure this stuff out... and usually they should be figuring it out before folks like us.

I can say on the rare occasions this happens on my end, I might as well let my dog start playing from there on out its so ridulously, obvioulsy cheated/hacked.

BTW... go spend some time with a G-6 ISMO tech (Oorah USMC)... they can hack your alram clock with feedback from your stereo speakers, figurativly speaking of course, but honestly its why the USMC tossed cable to the curb was (1) its realibility on feedback; a focre that cannot be predicited with any level of certainty, and (2) when utilized properly; feedback can be 'disguised'  and can help gain access to a system with a high level of effecincy.

Sometimes I wonder if it isnt one omy my G-6'rs but I know they all got something called honor and integrity and they arent lookin to impress any young kids with their 'wicked awesome' gaming skillz so what would be the point?
