Thanks, I'm used that the sound just works, never had to choose another option then the one that was setup as default and since the rest of the sound worked, I didnt think it would have been the output choice.

I got most running properly now, Aircrafts are flying better and smoother then ever before, got a lot less wrong ATC commands(sending back and forth between the same 2 controlers), Progressive taxiing doesnt bug anymore, AP landings work fine for every aircraft I tried so far. The only serious problem is the screen going black, showing only parts of the view and I need to switch to map/choose aircraft etc, minimize the program and so back and forth, until I got normal view back. This mostly works, but it takes several minutes of going through different screens before it resets. It can start with going to map, or other screens, or when I pause the sim. Any ideas on how to fix this?
A second thing is that my ATC window disappears when I start or stop the push tractor.

Maybe this could help a bit about buffer

Hmmm, didnt have any problems all evening and could switch between different screens without any problems, but now I requested new IFR and everything starts over again.
I've been trying different pool sizes, but this doesnt seem to help.
Restarting the sim helps and not I cant seem to trigger the problem again, but question is: for how long?

Can it be the poolsize has to be tuned more precise and if so, how can I do this without having to try 490000000 different options? Or is there something else that can be going wrong?

Another thing I find is that I get asked to report other traffic in sight and apparently they do see me, but I havent seen any other traffic at all, ever! For over a year, I havent seen any other flying aircraft then my own. Can this point to some issue is my system?

I noticed that the problems occur when the sim has been running for a while and now it only seems to get triggered by requesting new IFR. Restarting the sim solves it, but of course its not meant to stop every flight halfway and start over...

I tried the 8.000.000 setting and it seems to work a lot better already, but I'm still testing this. I changed it while my current flight, in which I already noticed this problem, was on pause, and in the same flight I cant trigger the problem anymore, only some glitches when returning from flightplan screen back to the flightscreen.
For further tuning, by what amounts should I go up or down?

No, I havent replaced the uiautomationcore.dll yet. What can I replace this with?

I also notice that when I change back to flightscreen, from several other screens, or when I use 'scroll lock' or 'pause break', I get a small item in lower right corner of my main screen with 3 squares, one green with a 1 in it, one white with an A in it and one green with a down pointing arrow in it. My guess is this is from the HP win7 version, but I cant tell for sure. Is this something I should worry about? Can I switch it off, somewhere?

quick question, I fond posts that tell me to replace the file in the syswow64 folder and others tell me to put it in the FSX folder, which one do I follow?

Far as I tried now, I cant replace the one in the syswow64 folder, because I need permission... I got admin access, so not sure what permission they ask for.

Demious, PLEASE listen to Daube here!!!

I suggest that you make sure all of your drivers are installed for your sound. If you did not get a CD or DVD for the mother board you will have to go to the web site of the manufacturer and down load it.
