The documentation says

readframes(
n)
        Reads and returns at most n frames of audio, as a string of
        bytes.
        
Note the "at most n frames". Most I/O functions work like this, they try
to give you as much data as you request but if they get interrupted by a
signal or something else they may return less than that. What happens if
you call readframes() again?
