Direct Sound error when selecting Twin Otter?

[T Bone 0]

I have purchased and installed the Twin Otter Extended but having issues when I try and select certain (most) default liveries. For example when I select the “Alak Air” model it loads fine and I can fly it. However, when I select the Winair, or Moorrea , Yeti, BAW liveries in the selection screen I get a “DIRECT SOUND ERROR” that pops up after I select the aircraft.

In that error window it says something like “error openting wave file trim up”. Then if I OK it or hit X to close that window, a new error pops up that is almost the same thing but it might say “error opening wave file avionics master”. So I OK or X again and another one pops up with somthing just slightly different. So I go through closing about 20-30 of these errors and after the last one FSX crashes and goes to the desk top. If it doesn’t crash at that point, it crashes when I hit the fly now button to load the flight.

Any ideas what might be going on? I'm not good at solving computer problems and I have never had this problem before, even on my old Aerosoft Twin Otters (which I removed from the aircraft folder before installing Extended). Thanks.

Try to update DirectX.

Thanks for your help, however that didn't solve the problem as the same thing is happening after this update. I then also removed the aircraft from the my aircrafts folder and re-installed it to see if that made a difference, which it did not. Any other ideas?

Maybe updating Your sounddriver.
