So, To get all the features working like native A2DP (yummy) BT.
I use a Mixer tool called Voicemeeter. http://vb-audio.pagesperso-orange.fr/Voicemeeter/index.htm to control the outputs.
so here how its set up.
1. install Breakaway as normal select line1
2. install Voicemeeter or Banana (donate version, Which i prefer)
3. Breakaway Settings: output "Voicemeeter VAIO" then your prefered bitrate and what nots
4. Voicemeeter Select your Hardware outs. and Use Voice meeters internal mixer to control where your audio goes.
works well in multi sound card installations and does work with BT headsets although repairing requires restarting voicemeeter.
Voicemeter gets around the audio routing limitations of windows, also gives alternate I/Os for TS3 if you dont want it to be processed by BA.
hope people find it useful.
hope there is an update around the corner, its long overdue.
