BIG FPS Loss When Sound Is On - FSX

[Ellis Mansell 0]

Hello there, lately I have noticed that my FPS has gone a bit worse than usual. I tried lowering scenery and all that kind of stiff. But, I did notice that when I hit the "Q" button in FSX, the sound mutes but my FPS goes up (in some cases, its up to 15FPS!) ?

What could this even be? I of course wan't to fly with sounds but it looks like there's no way of solving this problem. And yes, I have tried to update my Realtek drivers, but still no difference at all. 

It would be much appreciated for any suggestions, thanks.

What plane/s is this happening with?  I have downloaded in the past a couple of aircraft that had sound folders over 50MB.

 

and it was like sitting at KLAX-photoreal and FPS dropping to 3 or 4.

It may be a PC issue. Most pcs use the onboard sound, which in older PC's uses teh CPU to process the sound which is stealing the cpu cycles from fsx.If that is so, go but a cheap sound card, will make a big difference.
