Having problems with Audio

I am not sure where to put this since I didn’t see any “audio” area, so it is going here for now.

I am running a Raspberry Pi 3B with LibreElec 7.0.3 and Kodi 16.1.

I am having problems with Audio selection. My wife’s friend bought her a bluetooth speaker and she INSISTS on using it when she watches TV. I don’t like it, it cuts out and is dicey so I want to use the TV audio. However there is no option to have it switch between available audio, so when the Bluetooth is there it will connect and play, but will use the TV all other times. Is there some way to easily hack this together?

I read about PulseAudo, but there seems to be a lot of people saying audio quality gets poorer on both devices, which I don’t want…..
