thanks for the help but that did'nt fix it .the problem im having is there are no switch clicks ,stewardess calls ,call outs ,warnings ,bells and wistles ,tcas ,radar alt callouts ,. ive been beating my head aginst the wall trying to figure it out. i recently upgraded to a better pc and i have not been able to get them to work at all.on my old pc i could get them to work if i reloaded the aircraft but only until about 200 ft agl then they would stop and not come back. i will do whatever it takes to get these sounds to work.

update
FIXED!!!!!! :D ;Di cant believe it! i installed the msvcr71.dll into the fsx root folder and whala. the only thing i havent heard is the collision avoidance system but i havent been close to another aircraft yet .i also would like to add that i love the new cockpit light setup i found here, the only gripe i had about the 757 [besides the sounds not working] was the night lighting. thank you for all your help.
