just check for self._queue.qsize() in advance

[emphasize]

There are different issues leading to this raise, but ultimately the loop is not capable to fill the queue - self.chunk_size=4096[bytes] - in timeout (default=5 seconds)

Above issue is getting negative size microphone chunks, but mathematically it would only require 4096 / 5 - 1 bytes sized chunks/sec to raise (what likely happened in other cases without warning logs about the size)

full_chunk += mic_chunk
while len(full_chunk) >= self.chunk_size:
     self._queue.put_nowait(full_chunk[: self.chunk_size])
     full_chunk = full_chunk[self.chunk_size:]

time.sleep(0.0)

_{(What is this 0.0 wait about?} ^{check period size <=> chunk size)}
