Hi, Thanks for the response!

Not the answer I was hoping for, but makes sense as to the limitation. 

Any ideas for possible workarounds? Would it be possible to mix elsewhere?  The 
Raspberry PI has built-in sound that should support dmix, could that output be 
routed to the bluetooth device somehow?
