Lost Sounds

[Sky High 166]

Hello all. Just bought and installed FE2. Seems a considerable improvement and I only have XP. However I notice in flying most planes that I cannot hear engine or machine-gun sounds when facing straight ahead, only the wind. I can hear them when I look left, right or behind. Is this correct, would wind wipe out the other sounds in this manner, or do I have a little problem, and if so, is there a solution? Thanks in advance.
