Radio Chatter missing after winning main FL campaign?

I finished the original singleplayer portion of the game and after I left Manhattan, I noticed all the radio chatter was missing from the game. I looked around to see if I can find info on this, but have been unable to. Anyone have a fix or a suggestion to get it back working?

thanks.

Radio chatter still works if I hail a ship but that's about it, from what I can tell.
