I don't have any idea if this is the result of the beta patch, but the problem coincidentally started after I installed the patch, soo....
Diamond City Radio no longer works. I can select it, but even after several minutes of waiting, I hear nothing. I double-checked the radio volume setting, which is on full (all the way up). Also, the Classical station works just fine. As does the Brotherhood transmission from the police station (when I get close enough to it). I'm in Lexington at the moment (near Corvega), so I can't imagine range would be an issue. I'm hoping it will fix itself the next time I save & restart the game, but wanted to post about it just in case it's an actual bug introduced by the patch...
Thanks!!!
