Just to let you FSX fans all know, the Airbus A320 Family (A318, A319, A320, and A321) CFM56 Sounds are officially released now for FSX by SkyHigh Flight Simulations
I have tested them and they are really great with several configuration options depending on your wingview positions.
And it's one of the greatest freeware sound packages around with all credit to their dedicated team.
