Bluetooth output when 2 devices connected

[userWPsyxBla8V]

Hi! Everyone, I have a strange issue but please bear with me, so on one of my cars I have a small Bluetooth adapter connected via aux to the amplifier/dec for music. So what happens is that i would issue connect my buds+ and the adapter at the same time with the phone, when I would play music it used to automatically go through the adapter and hence played in the car where as any calls (their audio) would be re directed to the buds+, recently this has stopped happening the music audio has stopping going through the adapter unless I disconnect the buds or close their permission for audio(in the Bluetooth settings) any idea how to get back to how it was? I never set anything beforehand and didn't do any tinkering, just saw it was a cool feature. 

Thank you

Also I didn't have to do it before why now?

So from what I found out is that when connecting 2 devices via Bluetooth, the phone automatically sends the audio through the last connected device. So the potential fix for me was that first I would connect the buds then the adapter, this way I'd select and play any song on the adapter and when I receive a call I'd select the buds from the Bluetooth selection list. And after ending it would simply go back to playing the music on the adapter.
