Hi,

I can't comment "Bluez", I don't know how this works.
Anyway, it's Still incorrect, since only one sound server could grab the
audio device, the other sound sever needs to use the sound server
connected to ALSA.

                     +-------------+
                     | Application |
+-------------+      +-------------------+
| Application |      | One sound server  |
+----------------------------------------+
| Another Soundserver connects with ALSA |
+------------+---------------------------+
| ALSA connects software and hardware    |
+----------------------------------------+
| Hardware                               |
+----------------------------------------+

That's simplified, but in this context IMO good enough.
