[LAU] How to play multiple bluetooth (BT 4.0) audio receiver ?

[Winfried Ritsch]

Hello,

I just did some research but couldn't find any satisfying answer and I am not 
an BT specialist. So before digging deeper in the BT-world I want  ask here if 
anybody already has an solution and if it could work theoretically ?

Here my  state of research:

Since BLuez >= 5.0 dropped ALSA [1] I tried using pulseaudio (can route it 
trough jackd). I connected a BK8000L module (sure hifi) via bt-manager and 
pulseaudio works fine. I try to connect a second, the first one gets 
disconnected so only one is audio device seems to be  possible at the same 
time.

As a second solution I tried the alsa implementation: bluez-alsa  [2], but
I didn't succeed to use it via jackd (didnt try hard) and it has the same 
behaviour with aplay on an first try on command line.

Any ideas are appreciated.

Purpose: simple distributed audio-system adding BT speaker for sound 
installations, the first try two BT-Speaker used each mono, forming a stereo 
pair.
