I already posted in the enforcement forums but I haven't got any reply there. Its been over 2 weeks now and no one on xbox support seems to care.
My communication ban was lifted oct 3rd. Still no one can hear me in the party-chat or in the in-game chat.
I followed all kind of troublesteps but nothing works.
I know for a fact that its not a hardwear issue because everything works fine if I use a different account.
I had my gamertag since 2006 so I won't be starting a new one just to make it work.

I repeat 2!!! weeks and still no help!
