USB headset echoes when playing Battlefield 1942

[Guest]

Help, (please)

When using my analog 6.1 surround speakers all is fine
when running the game. All the latests EA BF42 patches
have been installed.

When I use my Plantronics DSP-500 USB headset, I hear
terrible repeated echos and makes playing the game
terrible using headset.

Here is the specs on my setup:
