Sub sound on the map screen

[Blacklight]

I was just curious if anyone knows if anything can be modded ti allow the rumbling of the engine sounds to play on the map screen without having to turn on the 3D window. I find it odd to switch to the map and suddenly have everything totally quiet. Same thing with Sub Command as well. It's not a big deal, but getting the audio to play there as well will do wonders for my imersion factor.
