Engine sound cutoff when Alt-tabbing

[TLDspectre 4]

I was wondering if there's a setting that will allow engine sounds to keep playing when I Alt-tab (fullscreen) or switch windows (windows mode)? I still hear ATC (RC4), but the engine sounds cut out. I use Plan-G to track my flightplan and I lose engine sound when I do. Not a biggie, but it would be nice to hear the engines running continuously from an immersion perspective. Unchecking "Pause on task switch" keeps the plane flying but doesn't help with the sound cutoff; I was hoping maybe there's a fsx.cfg setting that might address this?

Anytime you shift focus to another program while running Flight Simulator the sound will stop. No fix for that.Todd
