I use "async I/O" by setting a callback with the function *
snd_async_add_pcm_handler*
Maybe ALSA uses signals internally but i cannot imagine why SIGIO is
delivered to my program
I merely use snd_async_add_pcm_handler and give as argument a function that
writes data to the soundcard
with snd_pcm_writei, as described here
