Strange problem with Sounds

Hello everyone,first of all thanx so much,for such a superb addon,and making it available as freeware is even greater.However I'm having a really strange problem with the sound in the cockpit.All the cockpit sounds seem to work normal,but the trim sound doesnt't work.The other thing thats not working are the radio altitude callouts during approach.Very seldom there is a callout,but mostly there are no callouts at all.Has anybody any idea how to solve this problem,or whats the reason?That would be great,because it contributes a lot to the feeling of realism in the plane.I'm at a loss here.I installed everything in order:Version 1.2,1.21,1.22,1.23a. I also added the fsound.dll line fs9.cfg and checked all the sound files are there.I also tried reinstalling everything,but the problem appears again.If anybody could help me with that issues, it would be great.Thanx a lot in advance, Corey
