Use function to get samples to be sent to fill audio buffers to a
level. This replaces the function that only shows how much data
is in the buffer.
This way the function itself can control how much data will be
sent.
Now rates above 1000 RX frames per second works. The bug hit when there
were more than one frame received during one function call. This happens
if the frame rate is above the main loop rate of 1000 frames per second.
