It doesn't seem to make any difference, unfortunately. Following
Duncan's idea does seem to work, however:

diff --git a/sndioctl/sndioctl.c b/sndioctl/sndioctl.c
index 4c4a85a..71ae298 100644
--- sndioctl/sndioctl.c
+++ sndioctl/sndioctl.c
_at_@ -1014,6 +1014,7 @@ main(int argc, char **argv)
                        perror("malloc");
                        exit(1);
                }
                for (;;) {
+                       fflush(stdout);
                        nfds = sioctl_pollfd(hdl, pfds, POLLIN);
                        if (nfds == 0)
