Voice plays through Speakers instead of Bluetooth

[JohnnyOnTheSpot]

I have kind of a weird problem that just started with the new ROM. I have an adapter that allows you to plug in a 3.5mm, and I have it running into my tape deck in my car to listen to music. I normally just have the bluetooth on, and when someone calls the music stops and I answer through the headset. Now everytime someone calls during this the call comes through the speakers and I need to unplug everything quick to get the call. It's become very annoying; does anyone know how I would fix this? Soft resets dont do anything, for the record. Thanks.
