None. The number of samples in a given block is not known (it depends on
the audio codec) nor fixed (filters can change block length). So the total
number of buffers is rather irrelevant.
Since blocks are not empty, there cannot be more than
AOUT_MAX_ADVANCE_TIME * maximum sample rate
* minimum sample per block / CLOCK_FREQ
<= 576000 decoded blocks in the pipeline at a time.
That's a lot though.

To be clear: counting blocks makes no sense.
