I don't know ... this may be a head scratcher ... Whenever I'm in a mission, or doing a free flight in FSX it effects the volume on my computer.  If I am listening to a livestream broadcast the sound will get low.  This also happens if I'm in the menu to go on a mission.  If I put the simulator on pause, the sound will return to regular volume.  When I unpause, it will decrease the sound again.  I have accelerator installed.  The specs for my FSX rig is listed as the main rig in my sig.  Thanks for reading my post. :Batting Eyelashes:

Have you tried making any changes in the FSX.cfg file yet?  It easy to try to see if it helps.

Also try.. Open Control Panel/Sound/Communications, Choose the "Do Nothing" option then apply!

Nothing to do with your FSX settings but your sound card settings. Somewhere you have a volume equalization setting turned on or a setting that that tells Windows what to do when multiple programs want to access your sound card. That is where you should look.

Well yes indeed ... going into the control panel to the sound and telling it to do nothing did the trick ... thank you so much for your help.  Problem Solved! :lol:

No problem!  I get lucky sometimes!  Hope KLAS  scenery is looking better for you!
