Not sure. The general logic of snd_pcm_recover should be like this:
for (;;) {
if ((err = snd_pcm_writei(....)) >= 0)
/* Success */
break;
/* Failure, try to recover */
if ((err = snd_pcm_recover(..., err)) < 0) {
/* Failed to recover, we have a real issue */
fprintf(stderr, "Things went very wrong: %s", snd_strerror(err));
break;
}
/* Recovered, let's try another write */
}
This probably won't fix your issue, but it will shorten your code
quite a bit I would say and make it more robust.
snd_pcm_prepare() should be called only once after
init. snd_pcm_recover() will implicitly call _prepare() in all other
cases.
