Hello, recently I picked up a pair of the Tritton AX Pro's at the Penny
Arcade Expo In Boston. After coming home and setting them up, I found
that I could not hear through the headphones, though the people could
hear me in the Xbox Live Parties.

To fill in some blanks, I am using the new Xbox 360 Slim and I have the
optical cables plugged into the built in one. However, I am currently
using the older 360's component cables due to the Slim not coming with
an HD Component cable. I do not know if this is possibly causing the
problem, because when switching them with the standard AV cables, the
same problem occurred.

If you guys could provide any help, it would be much appreciated, as I
have been pretty excited to hook these guys up and use 'em. Thanks!
