3a072a63a6 removed buffer management for N>1 frames per burst
I decided removing this from the code and keeping everything simple for N=1 frames per burst. N>1 frames per burst need a completely rethinking of buffer management.

6a4fe14377 more debugging and buffer changes

3501b4f952 waiting for buffer
it seems we need to wait a little bit for our modulation data. There are some moments where audio output is stuck a little bit. Maybe python is sometimes faster than the buffer allocation or its a threading problem
