Saitek rudders FS9 Sound issue

Hi

Since then I have connected my Saitek rudders, I get some issues with the sound in the VC. Seems like moving the rudder makes some sounds disappear. Like pushing to the right and the sound from the right is cut out.

I did not have this problem before starting to use the rudders. This happens with every addon.

Rudders are controlled via FSUPIC. Use FS9.1.

I am using Active Camera, if it matters.

Any idea?

Thanks
