[Flexradio] Audio buffer sizes locked at 2048?

[Bill Tracey]

Somewhere between 1.4.5 preview 12 and 1.4.5 preview 16 it appears the 
buffer size selection on  Setup->Audio got disconnected from the value the 
code is actually using.  Currently (1.6.0) it looks like the block_size is 
locked to 2048 in audio.cs (private static int block_size1 is initialized 
to 2048 and never changed)  -- intentional, or collateral damage in trying 
to keep audio.cs from reaching out to Console.cs properties?
