void thread_test(Sound* s) {
	while(1) {
		usleep(200000); /* 0.2sec */
		s->loop_count = s->asound_read();
	}
}

So the function asound_read() is called 5 times per second. Since the function returns the number of blocks read, each containing 4k samples, the average value of loop_count should be 2.34 (= 0.2*(48000/4k)).

% ag --no-numbers loop_count log.txt | sort | uniq -c
      3 loop_count = 0
   2282 loop_count = 2
    992 loop_count = 3

After a short run of the program, the average value obtained is 2.30 (= (3*0+2282*2+992*3)/(3+2282+992)), and no -EPIPE error (overrun for capture) was observed during the run.
