FSX and Multiplayer Voice issue!

I know this might seem like bitting a dead horse but I asure you my issue is different.

Ok some info to narrow down the problem:

1) Windows 7 Pro 64bit

2) Onbard sound card and Logitech USB Headset

3) Windows Sound Devices set as:

Default Device = Onboard Sound Card

Default Comunication Device = USB Headset

4) FSX Sound Options set as:

Sounds = Onboard Sound Device(Speakers)

Voice = USB Headset(Speakers)

Here is the issue....When I play free flight everything works great VOXATC plays voice on headset and I get the engine sounds etc. from the Computer Speakers the issue is when I go Online. For some reason I can figure out the players communications always plays on the Default Device.

I test this by making the USB headset the default device. By doing that the sounds on FSX still play on the Computer Speakers and the multiplayer communications now play properly on the headset.

Now you might ask what is my problem? well the problem is that with the setup just mentioned FSX will work great but all my programs like Itunes, Windows Media Player, Internet explorer etc. will play on the headset. I just don't think that's the way it should work. But for some reason I don't know FSX likes to process Multiplayer communication through the Default Device only. Any help would be apreciated Thanks.
