Sound gone when using arrows in main panel

[30K 72]

Hi all,

yes it's strange.

My Q400 is all bright and shiny also with FS2Crew until i skip the 24 hrs checks with the arrows in the main panel.

The sound in the Q400 is then gone but not all of it (yeah strange) - the sound in the background is still there. Sound in the Background? Mh how to describe that... The sound when P3D is not focused. 

 Everything else works fine.

How can this be?

All those buttons do is change the checklist mode.

Do you have any buttons assigned to the stock P3D Sound toggle button?  I think it's Q.
