Anyone know how to keep FS sound on while not on focus?

While flying, at altitude, I often turn AP on and shrink (not minimize, just shrink the size) the window and do other stuff on my computer. But it annoys me that i can't hear the engines or the co-pilot in case of failures (fsPassengers). Anyone know how to make it so that you can hear MSFS sound while the window is not focused?

I don't think this is possible as the sound you hear in FS always is dependant on the window which is presently active.

Someone know a workaround, please share your knowledge.
