The poll_descriptors_count and poll_descriptors should return 2,
for example,
int my_poll_descriptors_count(snd_pcm_ioplug_t *io)
{
return 2;
}
int my_poll_descriptors(snd_pcm_ioplug_t *io, struct pollfd *pfds,
unsigned int space)
{
if (space < 2) {
error("Too little pfd\n");
return 0;
}
pfds[0].fd = fd0;
pfds[0].events = POLLOUT | POLLERR | POLLNVAL
pfds[1].fd = fd1;
pfds[0].events = POLLIN | POLLERR | POLLNVAL
return 2;
}
